A nationwide survey of college students was conducted and found that students spend two hours per class hour studying. A professor at your school wants to determine whether the time students spend at your school is significantly different from the two hours. A random sample of fifteen statistics students is carried out and the findings indicate an average of 1.75 hours with a standard deviation of 0.24 hours. Given the following printout, what can you determine?
A) The alternate hypothesis is 2
B) You should accept the null hypothesis at the 0.05 level of significance.
C) There is less than a 1% chance of getting these results if the null hypothesis is true, so you have very strong evidence to suggest that the average number of study hours is different from 2.
D) You should reject the null hypothesis at the 0.05 level of significance, but accept it when testing at the 0.01 level of significance.
E) You should accept the null hypothesis at the 0.05 level of significance, but reject it when testing at the 0.01 level of significance.
