Question

A medical researcher examined the number of asthma attacks patients had both before and while using an advanced air purifier. Seven patients were included in the study. The number of asthma attacks for each patient before and during using the air purifier is reported below. Use α = .05, 2-tailed.

Patient	Before Purifier	During Purifier
1	6	4
2	9	7
3	11	5
4	6	4
5	7	3
6	9	6
7	5	4

a.State the null and alternative hypotheses below.

b.What type of test should be run on the data (be specific with the exact name of the test)? For example, don’t just state “t test,” but the specific t test used.

c.What is the conclusion of the hypothesis test? State the p-value and the decision about the hypothesis test below. (Don’t write the results here – that will be done in (e) below – just state p and whether H₀ is rejected.)

d.What is the effect size for the study? (1) Calculate and report the effect size below. (2) Indicate the magnitude of the effect size according to Cohen’s standards and (3) interpret what the effect size means in terms of standard deviation units.

e.Write the results of the test in APA format below. (Hint: This type of write-up would be structured in a similar fashion to what you see in your text.)
