A simple random sample of 45 men from a normally distributed population results in a standard deviation of 11.5 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. (b) Looking for X2 test statistic (C ) P Value State conclusion

A simple random sample of 33 men from a normally distributed population results in a standard deviation of 8.2 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. b. Compute the test statistic; χ2 = ___ (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. (choose one from each ( x, y) set)

A simple random sample of 47 men from a normally distributed population results in a standard deviation of 12.4 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. b. Compute the test statistic: x^2= 70.73 c. Find the P-value: P-value= (round to four decimal places as needed)

A manufacturer designed an experiment to compare the differences between men and women with respect to the times they require to assemble a product. A total of 15 men and 15 women were tested to determine the time they required, on average, to assemble the product. The time required by the men had a standard deviation of 4.5 minutes, and the time required by the women had a standard deviation of 2.8 minutes. Do these data show that the amount of time needed by men is more variable than the amount of time needed by women? Use $\alpha=0.05$ and assume the times are approximately normally distributed. a. Solve using the $p$ -value approach. b. Solve using the classical approach.
