The police reported that the average driver exceeds the 50 miles per hour speed limit by more than 9 miles per hour on the busiest street in a small town. A sample of 63 randomly selected cars were clocked by airplane radar. The average speed was 57.5 miles per hour, and the standard deviation of the speeds was 4.17 miles per hour. Determine if the average speed is greater than what the police department reported. Which parameter(s) are you given? Mark all that apply. p μ σ none Which statistic(s) are you given?

Babies: A sample of 25 one-year-old girls had a mean weight of 24.1 pounds with a standard deviation of 4.3 pounds. Assume that the population of weights is normally distributed. A pediatrician claims that the standard deviation of the weights of one-year-old girls is greater than 7 pounds. Do the data provide convincing evidence that the pediatrician's claim is true? Use the =α0.05 level of significance.

A. Suppose we wish to make an estimate of the proportion of the population that has ever been arrested. We take a random sample of 500 people. In this sample, 10% of the respondents report having ever been arrested. Construct a 95% confidence interval for the proportion of people in the population who have been arrested. 2. Interpret, in words, the meaning of this interval.
A population of score has μ = 44. in this population, a score of X = 40 corresponds to z = -0.50. What is the population standard deviation?
