Answer 1

The provided sample mean is  Xbar = 1.73

and the sample standard deviation is s = 1.845

and the sample size is n = 1038.

Null and Alternative Hypotheses

The following null and alternative hypotheses need to be tested:

Ho: μ = 1.6; Rikers sample mean of open or unresolved cases to the national average of open cases for arrestees is equal to 1.6

Ha: μ ≠ 1.6: Rikers sample mean of open or unresolved cases to the national average of open cases for arrestees. is significantly different from 1.6
