A psychologist noted that people have more difficulty sleeping in a bright room than in a dark room. She measured whether the intensity of the light could predict the time it took a sample of 4 participants to fall asleep. The data for this hypothetical study are listed in the following table.

Intensity of
Light (in watts)
Time It Took to
Sleep (in minutes)
X Y
5 9
10 19
20 29
40 35


Compute an analysis of regression for this hypothetical study. (Round your answers to two decimal places.)

Source of
Variation
SS df MS Fobt
Regression
Residual (error)

Make a decision to retain or reject the null hypothesis. (Assume alpha equal to 0.05.)

Retain the null hypothesis. Reject the null hypothesis.

Answer #1

Answer:

By using minitab, Path: Stat > Regression > Regression > Fit Regression Model

Here, P value 0.077 > 0.05

Hence, Accept the null hypothesis.

Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of SAD patients to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their...
