A study time survey is conducted of 39 UGA students and a mean x-bar=110 minutes is obtained. Test whether the UGA study times differ from the national average of 120 min.? Assume study times have a normal distribution with a known standard deviation of =30 minutes. Use the 5% significance level. | What is the correct interpretation of the hypothesis testing result at the 5% level of significance? 1) = The UGA study times were greater than the national average. 2) = The UGA study times are different from the national average. 3) = There was no difference between the UGA and national study times. ______________________________ Note: Enter integer 1, 2, 3 No decimal
