Question
Solve the problem.
The number of violent crimes committed in a day possesses a distribution with amean of 4.8 crimes per day and a standard deviation of 2 crimes per day. A random sample of 100 days was observed, and the sample mean number of crimes for the sample was calculated. Describe the sampling distribution of the sample mean.
The number of violent crimes committed in a day possesses a distribution with a

The mean speed of a sample of vehicles along a stretch of highway is 68 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 65 miles per hour and 71 miles per hour. (Assume the data set has a bell-shaped distribution.)

In a recent awards ceremony, the age of the winner for best actor was 27 and the age of the winner for best actress were 47. For all best actors, the mean age is 42.7 years and the standard deviation is 7.7 years. For all best actresses, the mean age is 32.9 years and the standard deviation is 11.2 years. (All ages are determined at the time of the awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain. Since the z score for the actor is z= and the z score for the actress is z=,the▼actress actor had the more extreme age.arrow_forward
- The speed vehicles traveled on a local highway was recorded for one month. The speeds ranged from 47 mph to 62 mph with a mean speed of 55 mph and a standard deviation of 6 mph. The quartiles and median speeds were 50 mph, 59 mph, and 52 mph. Suppose increased patrols reduced speeds by 7%. Find the new mean and standard deviation. Express your answer in exact decimals. Choose the best answer below: A. Mean: 3.85 mph, SD: 0.42 mph B. Mean: 58.85 mph, SD: 6.42 mph C. Mean: 51.15 mph, SD: 6 mph D. Mean: 58.85 mph, SD: 6 mph E.
