Question 9 1 pts In Spring 2017, data was collected from a random selection of STA 2023 students. One of the questions asked how many hours they had slept the previous night. The 90% confidence interval comparing underclassmen to upperclassmen was (0.015, 0.9153). For the hypothesis Ho:mu 1-mu2 - Oversus Ha:mul-mu2 does not equal o, what would be the p-value? Can not be determined. p-value > 0.10 p-value - 0.10 p-value <0.10
