Question

Dr. Addison believes that going through a training program will increase weekly reading. College students read a mean of 2.3 days a week with a variance of 4.00 days. Dr. Addison's sample of 30 students read a mean of 3.2 days a week. What can be concluded with an α of 0.05?

c) Obtain/compute the appropriate values to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value = ________ ; test statistic = ___________
Decision: ***(choose one)*** 1. Reject H0 or 2. Fail to reject H0

d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[ ], [ ]

e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and select "na" below.
d = ___________ ;   *(choose one)1. na 2. trivial effect 3. small effect 4. medium effect 5. large effect
r² = ___________ ;   *(choose one)1. na 2. trivial effect 3. small effect 4. medium effect 5. large effect

f) Make an interpretation based on the results. (choose one)

1. ) Individuals that went through the training program did significantly more reading than college students

2.) .Individuals that went through the training program did significantly less reading than college students.   

3.) The training program has no significant effect on weekly reading.

Answer 1

(f)

Option: 1. ) Individuals that went through the training program did significantly more reading than college students.
