I need the sample mean and sample standard deviation.
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.

Determine whether the statement is true or false. If it is false, rewrite it as a true statement. A sampling distribution of a sample mean is normal only if the population is normal. Choose the correct answer below. O A. The statement is false. A sampling distribution of a sample mean is approximately normal if either n ≥ 30 or the population is normal. B. The statement is false. A sampling distribution of a sample mean is never normal. O C. The statement is false. A sampling distribution of a sample mean is approximately normal only if n ≥ 30. OD. The statement is true.
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 & using the given sample statistics. Claim: p < 0.13; x = 0.05; Sample statistics: p=0.12, n = 25 Can the normal sampling distribution be used? A. No, because nq is less than 5. O B. No, because np is less than 5. OC. Yes, because both np and nq are greater than or equal to 5. D. Yes, because pq is greater than α = 0.05.
