The ACT standardized college admission was given in three rooms at a local testing site. A complaint was filed that one of the testing conditions of each room were not the same and caused a difference of scores. You have been asked to provide a statistical analysis to support or refute the claim. Determine your hypotheses, run the appropriate test, and provide the appropriate conclusion.

The scores from each of the three rooms were:

Room A	Room B	Room C
21	17	19
16	24	16
14	29	22
17	21	15
12	17	16
19	30	13
34	22	29
14	16	17
26	12	27
36	19	27

Expert Solution

H0 : There is no significant difference of scores between the sample.
H1 : There is significant difference of scores between the samples.
F(9,20) at 0.05 level of significance

=2.3928

As calculated F=1.6778<2.3928

So, H0 is accepted, Hence there is no significant difference of scores between samples

The Dean of Instruction at a local college requested that a new standardized test for an introductory statistics course be developed with the requirement that it should have µ = 100 and σ = 10. A class of 30 students complete the new test with a mean grade of 95. Conduct a hypothesis test at α = .05 to determine whether the claim that µ = 100 can be supported. Use the p-value approach and complete the following to show...
