Question

Conduct a complete hypothesis test:

Researchers have often noted increases in nonviolent crime during the warm weather months. Over the past 30 years, a particular precinct has noted an average of ? = 14 nonviolent crimes during the summer months. Assume the distribution is nearly normal with ? = 3. For a sample of n = 4 weeks in which the daily temperature was extremely hot, the weekly average of non-violent crimes was M = 17.25.

What is the independent variable?

Nonviolent crimes

What are the levels of the independent variable?
What is the level of measurement of the independent variable?
What is the dependent variable?
What is the level of measurement of the dependent variable?
If you were to graph your results, what type of graph would you make? Explain.
Is there a significant difference in the number of non-violent crimes during hot weather
days compared to typical days? Test at the alpha = .05 level.
Compute Cohen’s d.
Give a full APA summary of your findings.
What is the probability that we made a Type I error? What would this probability be in
terms of the independent and dependent variables?
Is there a risk of a Type II error? Explain.
