A simple random sample of 49 men from a normally distributed population results in a standard deviation of 7.8 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 t Complete parts (a) through (d) below. sample results with a 0.05 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. a. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: o= 10 beats per minute O B. Ho: o+ 10 beats per minute H:0 = 10 beats per minute H:o< 10 beats per minute OC. Ho: 0210 beats per minute H:o< 10 beats per minute O D. Hn: 0 = 10 beats per minute H:0# 10 beats per minute b. Compute the test statistic. (Round to three decimal places as needed.) c. Find the P-value. P.value = (Round to four decimal places as needed.) d. State the conclusion. V Ho, because the P-value is V the level of significance. There is evidence to warrant rejection of the claim that the standard deviation of men's pulse rates is equal to 10 beats per minute.

In a certain country the heights of adult men are normally distributed with a mean of 70.2 inches and a standard deviation of 2.7 inches. The country's military requires that men have heights between 66 inches and 79 inches. Determine what percentage of this country's men are eligible for the military based on height. The percentage of men that are eligible for the military based on height is nothing%. (Round to two decimal places as needed.)
Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has a mean ratio of 5.9. Suppose that 100 fossil humerus bones were unearthed at a site where Species A is known to have flourished. (We assume that all bones are from the same species.) The length-to-width ratios of these bones have a sample mean 5.6 and sample standard deviation 0.25. Can we conclude that the mean ratio of these bones is significantly smaller than those of Species A? Test with a 0.01 significance level. What is the standard error?

A newspaper article noted that the mean life span for 35 male symphony conductors was 73.2 years with a standard deviation of 8.7 . Males in the general population have a mean life span of 69.5 years.
