Dr Hughes researches the pattern of vending machine use on c

Dr. Hughes researches the pattern of vending machine use on campus. He has found that two factors increase the use of vending machines (0-10) in college; one is time of the semester and one is time of day. He wants to determine if these two factors influence one another to form a more specific pattern of vending machine use. Dr. Hughes goes to several locations on campus to watch the use of vending machines. He records the time of day and the time within the semester. He later then transposes those times into groups (time of day 1=morning, 2=afternoon, 3=evening, 4=late night; time of semester 1=early, 2=late).

What are the null and alternative hypotheses (use the appropriate symbols not words)?

What is the appropriate test for the researcher to use? Why?

Solution

Independent=time of the semester and time of day

Dependent= the pattern of vending machine use on campus

Hypotjesis:

Ho: mean(time of semester)=Mean(time of day)

H1:mean(time of semester)!=Mean(time of day)

2 independent sample t,to be used.

Dr. Hughes wants to determine if these two factors influence one another to form a more specific pattern of vending machine use. Dr. Hughes goes to several locations on campus to watch the use of vending machines.SO, we have two different sample one is time of samester and other is time of day.So, 2 independent sample t,to be used.

tests assumptions is that two sample is independent and with population with equal variance.
