Decide whether the normal sampling distribution can be used, If it can be used, test the claim about the population proportion p at the given level of significance a using the given sample statistics. Claim: p#0.25, a=0.05; Sample statistics: p=0.22, n= 200 Can the normal sampling distribution be used? O A. No, because np is less than 5 O B. Yes, because pg is greater than a=0,05. O C. No, because ng is less than 5. O D. Yes, because both np and ng are greater than or equal to 5. State the null and alternative hypotheses. O A. Ho p20.25 H3 p<0.25 O B. Ho p=0.25 H p 0.25 OC. Ho ps0.25 H p>0.25 O D. The test cannot be performed. Determine the critical value(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice O A. The critical value(s) is/are (Round to two decimal places as needed. Use a comma to separate answers as needed.)

Assume the samples are random and independent, the populations are nomally distributed, and the population variances are equal. The table available below shows the prices (in dollars) for a sample of automobile batteries. The prices are classified according to battery type. At a = 0.10, is there enough evidence conclude that at least one mean battery price is different from the others? Complete parts (a) through (e) below. E Click the icon to view the battery cost data. (a) Let u1. P2. H3 represent the mean prices for the group size 35, 65, and 24/24F respectively. Identify the claim and state Ho and H. H Cost of batteries by type The claim is the V hypothesis.

Decide whether the normal sampling distribution can be used. If it can be​ used, test the claim about the population proportion p at the given level of significance α using the given sample statistics. ​Claim: p≠0.21​; α=0.05​; Sample​ statistics: p=0.16​, n=175       Can the normal sampling distribution be​ used?     A. ​Yes, because both np and nq are greater than or equal to 5. Your answer is correct.   B. ​No, because np is less than 5.   C. ​Yes, because pq is greater than α=0.05.   D. ​No, because nq is less than 5. State the null and alternative hypotheses.     A. H0​: p≥0.21 Ha​: p<0.21   B. H0​: p=0.21 Ha​: p≠0.21 This is the correct answer.   C. H0​: p≤0.21 Ha​: p>0.21 Your answer is not correct.   D. The test cannot be performed.

Assume a population of 3, 4, and 11. Assume that samples of size n = 2 are randomly selected with replacement from the population. Listed below are the nine different samples. Complete parts a through d below. 3,4 3,3 a. Find the value of the population standard deviation o. S ▼ 3,11 ▼ ■ 1 | 4,3 4,4 C (Round to three decimal places as needed.) b. Find the standard deviation of each of the nine samples, then summarize the sampling distribution of the standard deviations in the format of a table representing the probability distribution of the distinct standard deviation values. Use ascending order of the sample standard deviations. Probability (Type integers or fractions.) c. Find the mean of the sampling distribution of the sample standard deviations. The mean of the sampling distribution of the sample standard deviations is. 4,11 11,3 11,4 11,11
