In a random sample of 46 Denver neighborhoods, the crime rates per 1000 population were found to have a mean of 64.2 and a sample standard deviation of 27.9. Find a 95% confidence interval for the population mean crime rate of all Denver neighborhoods.
Interpret the confidence interval in context of the problem and find all of the following
| x-bar |
| std dev |
| n |
| Confidence Level |
| Margin of Error |
| Point Estimate |
| Lower Limit |
| Upper Limit |
Thank you!
