Question

The owners of the Syfy channel are interested in whether watching the Syfy channel causes people to become "geeky," and if so, whether any such effects depend on a person's gender. They hire a researcher to design and carry out the appropriate study. The researcher randomly assigns an equal number of men and women to watch 0, 3, 5, or 9 hours of the Syfy channel each week for 6 weeks. What is the research hypothesis for the main effect of hours watched? Group of answer choices On average, men are geekier than women when watching fewer hours but less geeky than women when watching more hours of the Syfy channel. On average, watchers differ in their geekiness levels across the various hours of the Syfy channel watched. On average, watchers are equally geeky regardless of the hours of the Syfy channel they watch. On average, men and women differ in their geekiness levels.

Answer #1

Queston:

What is the research hypothesis for the main effect of hours watched?

Correct option:

**On average, men and women differ in their geekiness
levels.**

Explanation:

The Research Question is: whether watching the Syfy channel causes people to become "geeky," and if so, whether any such effects depend on a person's gender

So, we have:

H0: Null Hypothesis: (On average, men and women do not differ in their geekiness levels)

HA: Alternative Hypothesis: (On average, men and women differ in their geekiness levels) (Claim)

A researcher was interested in comparing the amount of time (in
hours) spent watching television by women and by men. Independent
simple random samples of 14 women and 17 men were selected, and
each person was asked how many hours he or she had watched
television during the previous week. The summary statistics are as
follows.
Use a 0.05 significance level to test the claim that the mean

You are interested in whether the average lifetime of Duracell
AAA batteries is less than the average lifetime of Energizer AAA
batteries. You lay out your hypotheses as follows: Null Hypothesis:
μ1 ≥ μ2, Alternative Hypothesis:
μ1 < μ2 (Duracell = Group 1, Energizer =
Group 2). You perform an experiment on 23 randomly selected
Duracell AAA batteries and 33 randomly selected Energizer AAA
batteries and test them using a battery drainer. The Duracells had
an...
