1. Using the .05 level of significance, run a z- test given the following:
n = 74, p = 5/74 Po = 10%
A. The computed z value 0.91 is greater than the critical value -1.96.
B. Based on the evidence on hand that the computed z statistic - 0.91 lies outside the rejection region, we cannot reject the null hypothesis.
C. The computed z value -0.91 is lesser than the critical value -1.96.
D. Based on the evidence on hand that the computed z statistic 0.91 lies inside the rejection region, we cannot reject the null hypothesis.

The proportion of packs that contain less than 340g is approximately 0.0918 or 9.18%. The likelihood of a pack containing exactly 330g cannot be determined without additional information.

To find the proportion of packs that contain less than 340g, we need to calculate the z-score and use the standard normal distribution table. The Calculating z-score:

z = (x - µ) / σ

Where x is the value we want to find the proportion for (in this case, 340g), µ is the mean (350g), and σ is the standard deviation (4.18g).

Substituting the values, we have:

z = (340 - 350) / 4.18 ≈ -2.39

Next, we look up the corresponding z-score in the standard normal distribution table. The area to the left of -2.39 represents the proportion of packs that contain less than 340g. Consulting the table, we find that the area is approximately 0.0091 or 0.91%.

Therefore, the proportion of packs that contain less than 340g is approximately 0.0918 or 9.18%.

To determine the likelihood of a pack containing exactly 330g, we need more information. Specifically, we would need the probability density function (PDF) of the distribution to calculate the exact likelihood. Without the PDF, we cannot determine the likelihood of a specific weight like 330g.

The explicit formula for the sequence [tex]\(a_n\)[/tex] is:

[tex]\(a_n = \begin{cases} 4n + 3 & \text{if } n \text{ is even} \\ 4n - 2 & \text{if } n \text{ is odd} \end{cases}\)[/tex]

To find an explicit formula for the sequence [tex]\(a_n\)[/tex] that satisfies the recurrence relation [tex]\(a_n = 2n-1 + 2a_{n-2}\)[/tex] with initial conditions [tex]\(a_1 = 2\)[/tex] and [tex]\(a_2 = 7\)[/tex], we can proceed as follows:

First, let's examine the first few terms of the sequence:

[tex]\(a_1 = 2\)\\\(a_2 = 7\)\\\(a_3 = 2(3) - 1 + 2a_1 = 5 + 2(2) = 9\)\\\(a_4 = 2(4) - 1 + 2a_2 = 8 + 2(7) = 22\)\\\(a_5 = 2(5) - 1 + 2a_3 = 9 + 2(9) = 27\)\\[/tex]

We can observe that the even-indexed terms [tex]\(a_2, a_4, a_6, \ldots\)[/tex] are increasing by a factor of 2, while the odd-indexed terms [tex]\(a_1, a_3, a_5, \ldots\)[/tex] are increasing by a factor of 3. This pattern suggests that we can split the sequence into two separate sequences:

For even-indexed terms:

[tex]\(b_n = a_{2n}\)[/tex]

For odd-indexed terms:

[tex]\(c_n = a_{2n-1}\)[/tex]

Let's find explicit formulas for both [tex](\(b_n\))[/tex] and [tex](\(c_n\))[/tex]:

1. Even-indexed terms [tex](\(b_n\))[/tex]:

The recurrence relation becomes:

[tex]\(b_n = 2(2n) - 1 + 2b_{n-1}\)[/tex]

To simplify the formula, let's rewrite [tex]\(b_n\)[/tex] as [tex]\(b_{n+1}\)[/tex] (i.e., shifting the index by 1):

[tex]\(b_{n+1} = 2(2n + 2) - 1 + 2b_{n}\)[/tex]

Subtracting the two equations, we get:

[tex]\(b_{n+1} - b_n = 4\)[/tex]

This is a simple arithmetic progression with a common difference of 4. To find an explicit formula for [tex]\(b_n\)[/tex], we can use the formula for the nth term of an arithmetic progression:

[tex]\(b_n = b_1 + (n - 1) \cdot \text{{common difference}}\)[/tex]

Substituting [tex]\(b_1 = a_2 = 7\)[/tex] and the common difference of 4, we have:

[tex]\(b_n = 7 + (n - 1) \cdot 4 = 4n + 3\)[/tex]

2. Odd-indexed terms [tex](\(c_n\))[/tex]:

The recurrence relation becomes:

[tex]\(c_n = 2(2n-1) - 1 + 2c_{n-1}\)[/tex]

Similar to before, let's rewrite [tex]\(c_n\)[/tex] as [tex]\(c_{n+1}\)[/tex]:

[tex]\(c_{n+1} = 2(2n + 1) - 1 + 2c_{n}\)[/tex]

Subtracting the two equations, we get:

[tex]\(c_{n+1} - c_n = 4\)[/tex]

Again, this is an arithmetic progression with a common difference of 4. Applying the formula for the nth term of an arithmetic progression:

[tex]\(c_n = c_1 + (n - 1) \cdot \text{{common difference}}\)[/tex]

Substituting [tex]\(c_1 = a_1 = 2\)[/tex] and the common difference of 4, we have:

[tex]\(c_n = 2 + (n - 1) \cdot 4 = 4n-2[/tex]

1) [tex]\cdot 4 = 4n - 2\)[/tex]

Now that we have explicit formulas for both [tex]\(b_n\)[/tex] and [tex]\(c_n\)[/tex], we can combine them to obtain the explicit formula for the original sequence [tex]\(a_n\)[/tex]:

For even-indexed terms, [tex]\(a_{2n} = b_n = 4n + 3\)[/tex]

For odd-indexed terms, [tex]\(a_{2n-1} = c_n = 4n - 2\)[/tex]

Therefore, the explicit formula for the sequence [tex]\(a_n\)[/tex] is:

[tex]\(a_n = \begin{cases} 4n + 3 & \text{if } n \text{ is even} \\ 4n - 2 & \text{if } n \text{ is odd} \end{cases}\)[/tex]

Answer:

Step-by-step explanation:

The comparison of systolic blood pressure in the sitting and standing positions is an example of testing the difference between matched pairs from two dependent populations.

The scenario described involves measuring the systolic blood pressure of the same set of patients in two different positions (sitting and standing). This creates a dependency between the measurements because each patient serves as their own control. In this case, the appropriate statistical test would be a paired t-test or a related test for dependent samples.

Two means from independent populations: This option would be suitable if the measurements were taken from two different groups of patients who were independent of each other, but in this case, the same individuals were measured in both positions. Two population proportions: This option would be applicable if the data involved proportions or categorical variables, rather than continuous measurements like blood pressure.

Matched pairs from two dependent populations: This option accurately represents the scenario described, as the measurements were taken from the same individuals in both positions, making them dependent on each other.

The theoretical mean for a draw from a Poisson distribution with parameter λ is equal to λ itself. In this case, λ = 37, so the theoretical mean is also 37.

Explanation:

The Poisson distribution is commonly used to model the number of events occurring within a fixed interval of time or space, when these events occur with a known average rate λ. The probability mass function of the Poisson distribution is given by P(X=k) = (e^(-λ) * λ^k) / k!, where X represents the random variable representing the number of events and k is the observed value.

The Central Limit Theorem states that when independent random variables are added, their sum tends toward a normal distribution, regardless of the shape of the original distribution. For a Poisson distribution, as the parameter λ increases, the distribution becomes more symmetric and bell-shaped, resembling a normal distribution.

Since the mean of a Poisson distribution is equal to its parameter λ, the theoretical mean for a draw from a Poisson distribution with parameter 1 = 37 is 37. This means that, on average, 37 events are expected to occur within the given interval.
