If α = 0.16, and β = 0.19, complete the following questions by
inserting the appropriate probability of each. (Response
must be in decimal form) (Use these values for
this question only)
The statistical decision is to fail to reject null, and
H0 is really true (i.e., a correct decision)

For the following questions, refer to the following scenario: The local police chief started a “crimeline” program some years ago and wonders if it’s really working. The program publicizes unsolved violent crimes in the local media and offers cash rewards for information leading to arrests. The police chief wants to know: Is there a difference in the arrest rate for crimes that are publicized compared to those that are not? Results from random samples of both types of crimes are...

Suppose you want to test the following hypotheses: H0: p ≥ 0.4 vs. H1: p < 0.4. A random sample of 1000 observations was taken from the population. Answer the following questions and show your Excel calculation for each question clearly: (a) Let p ̂ be the sample proportion. What is the standard error of sample proportion (i.e., σ_p ̂ ) if H0 is true? (b) If the sample proportion obtained were 0.38 (i.e., p ̂=0.38), what is its p-value?...
