1. A sample of data is collected from a group of college students (X = 112, Sx = 12, N = 58). It is hypothesized that members of
this group have higher test scores than the general population (u = 100, o = 15). What test do you conduct? Don't do the test,
just name the test and list the relevant equation for the test statistic.

A professor offered a course half online and half in person.The professor hypothesized that students
were spending less time engaged with course during online than in person,At the end of the semester
students were asked to provide the amount of time they tended in a week. The weeks were classified as online or in person and the average amount of time for 15 weeks is given below.
Online: 4 3 5 6 2 2 4 7 5 4 3 2 6 6 3
In person: 5 5 4 7 3 4 4 6 4 5 3 4 5 8 4
Test the hypotheses at (alpha= 0.05) level of significance using the 5 step hypotheses testing. Make
sure you clesrly state the null and alternative hypotheses. Round your answer to 2 decimal places;
