Question

Dr. Addison hypothesizes that going through a training program will increase weekly reading. College students read a mean of 2.4 days a week with a standard deviation of 1.9 days. Dr. Addison's sample of 28 students read a mean of 2.5 days a week. What can be concluded with an α of 0.10?

a) What is the appropriate test statistic?
---Select--- na / z-test / one-sample t-test/ independent-samples t-test / related-samples t-test

b)
Population:
---Select--- students / individuals exposed to the training program / college students / days in the week (reading)
Sample:
---Select--- students / individuals exposed to the training program college students / days in the week (reading)

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:  ---Select--- Reject H0 / 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 =  ;   ---Select--- na/ trivial effect / small effect / medium effect / large effect
r² =  ;   ---Select--- na / trivial effect / small effect / medium effect / large effect

f) Make an interpretation based on the results.

Individuals that went through the training program did significantly more reading than college students.Individuals that went through the training program did significantly less reading than college students.    The training program has no significant effect on weekly reading.
