A study is conducted to compare the lengths of time required by men and women to assemble a certain product. Past experience indicates that the distribution of times for both men and women is approximately normal but the variance of the times for women is less than that for men. A random sample of times for 11 men and 14 women produced the following data: Men n1 = 11 s1 = 6.1 Women n2 = 14 82 = 5.3 Test the hypothesis that the variance for men is greater than for women. Use both p-value method and critical value approach. Use a=0.05.

Transcribed Image Text:4. A study is conducted to compare the lengths of time required by men and women to assemble a
certain product. Past experience indicates that the distribution of times for both men and
women is approximately normal but the variance of the times for women is less than that for
men. A random sample of times for 11 men and 14 women produced the following data:
Men
Women
n1 = 11
s1 = 6.1
n2 = 14
82 = 5.3
Test the hypothesis that the variance for men is greater than for women. Use both p-value
method and critical value approach. Use a=0.05.
