Question 1168600: Researchers were examining whether or not average prison sentence lengths for property offenders were different between California and Florida. The
researchers had access to population data from Florida, but not from California. The population data from Florida showed a mean sentence length of 22 months,with a standard deviation of 3.2. Sample data collected in California from 500 convicted property offenders showed a mean sentence length of 24 months.
1. When the researchers conducted a Z-Test for One Sample mean to examine
whether or not there was a significant difference in sentence lengths between
California and Florida, the null hypothesis would be:
a. Ho: μ = 500
b. H1: μ ≠ 500
c. Ho: μ = 24
d. Ho: μ = 22
e. Ho: μ ≥ 22
f. H1: μ ≠ 24
I got A am I correct?

Ho: mu=22 is the answer for seeing if there is a significant difference in sentence lengths between the states.
500 is the sample size, want the value of the mean.
24 is the sample value, not necessarily the value of the parameter.
