This Question: 1 pt 13 of 14 (3 complete) This Test: 14 pts poss A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are n = 196, x=6.51, s = 2.05. Use a 0.10 significance level to test the claim that the population mean of such ratings is less than 7.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. Ho: H 7.00 Hy : H 7.00 Hy : H # 7.00 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Ho. There is evidence to conclude that the mean of the population of ratings is 7.00.This Question: 1 pt 14 of 14 (4 complete) This Test: 14 pts possible A simple random sample of 50 men from a normally distributed population results in a standard deviation of 10.1 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. Complete parts (a) through (d) below. a. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: 6 = 10 beats per minute O B. Ho : # 10 beats per minute Hy: o # 10 beats per minute H1: 0= 10 beats per minute O C. Ho: 0 2 10 beats per minute O D. Ho : 6 = 10 beats per minute Hy : o
