Null hypothesis and critical value

Reference no: EM13109314

The heights were measured for nine supermodels. They have a mean of 67.1 and a standard deviation of 2.3 in. Use the traditional method and a 0.01 significance level to test the claim that supermodels have heights with a mean that is greater than the mean of 63.6 in. for women from the general population.

Choose the correct answer below:

a. Reject H0 since the test statistic 0.219 is not greater than the critical value 2.896.

b. Do not reject H0 since the test statistic 4.565 is greater than the critical value 2.896.

c. Reject H0 since the test statistic 4.565 is greater than the critical value 2.896.

d. Do not reject H0 since the test statistic 0.219 is not greater than the critical value 2.896.
