A sample mean, sample standard deviation, and sample size are given. Use the one-mean t-test to performthe required hypothesis test about the mean, μ, of the population from which the sample was drawn. Use theP-value approach. Also, assess the strength of the evidence against the null hypothesis.x = 22,298, s = 14,200, n=17, Ho: μ = 30,000, H₂: μ#30,000 x = 0.05.O A. Test statistic: t= -2.24. P-value = 0.0250. Reject the null hypothesis. There is sufficient evidence toconclude that the mean is different from 30,000. The evidence against the null hypothesis is strong.B. Test statistic: t= -2.24. P-value = 0.0399. Reject the null hypothesis. There is sufficient evidence toconclude that the mean is different from 30,000. The evidence against the null hypothesis is strong.O C. Test statistic: t= -2.24. P-value = 0.9601. Do not reject the null hypothesis. There is not sufficientevidence to conclude that the mean is different from 30,000. The evidence against the nullhypothesis is weak or none.O D. Test statistic: t= -2.24. P-value = 0.0200. Reject the null hypothesis. There is sufficient evidence toconclude that the mean is different from 30,000. The evidence against the null hypothesis is strong.

An IQ test is designed so that the mean is 100 and the standard deviation is 16 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 90% confidence that the sample mean is within 4 IQ points of the true mean. Assume that o = 16 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. ... The required sample size is (Round up to the nearest integer.) Would it be reasonable to sample this number of students? No. This number of IQ test scores is a fairly large number. Yes. This number of IQ test scores is a fairly small number. No. This number of IQ test scores is a fairly small number. Yes. This number of IQ test scores is a fairly large number.
