Detemine whether a normal sampling distribution can be used for the following sample statistics. If it can be used, test the claim about the difference between two population proportions p, and p, at the level of significance a. Assume that thesamples are random and independent.Claim: P, P2, a =0.01Sample Statistics: x, = 34, n, = 65, x2 = 35, n2 = 75O A. z=(Round to two decimal places as needed.)O B. The conditions to use a normal sampling distribution are not met.Calculate the P-value, if applicable. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.O A. P=(Round to three decimal places as needed.)O B. The conditions to use a normal sampling distribution are not met.State the conclusion of the hypothesis test, if applicable. Choose the correct answer below.O A. Since Pa, fail to reject Ho. There is not enough evidence at the a = 0.01 level of significance to support the claim.O C. Since P>a, reject Ho. There is enough evidence at the a = 0.01 level of significance to support the claim.O D. Since P Determine whether a normal sampling distribution can be used for the following sample statistics.

Information needed for the next two problems: A bored statistician is interested in researching length of commercial breaks on cable channels (ESPN, TNT, etc.) and comparing them to the length of commercial breaks on the networks (ABC, CBS, NBC, FOX). She times a random sample of commercials from each of the two types of broadcasts which are assumed to be normally distributed. Source n Mean(min.) Std. Dev. (min.) Cable 15 2.36 0.16 Network 12 2.18 0.13 Based on your previous answer for the upper bound and assuming the lower bound ratio of variances of cable to network is 0.5531, your conclusion about the spread of the variances of cable vs network commercials is O 1 is in the interval so statistically the same O O is in the interval so statistically the same O 1 is not in the interval so statistically different O O is in the interval so statistically not the same O 1 is in the interval so statistically not the same
In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.
Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.05 to test for a difference between the weights of discarded paper (in pounds) and weights of discarded plastic (in pounds). In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the weight of discarded paper minus the weight of discarded plastic for a household.

Which of the following is NOT a requirement of testing a claim about the mean of the differences from dependent samples? Choose the correct answer below. O A. The degrees of freedom aren- 2. O B. The samples are simple random samples. O C. The sample data are dependent. O D. Either the number of pairs of sample data is larger than 30 or the pairs have differences that are from a population having a distribution that is approximately normal, or both.
