A random sample of 160 car crashes are selected and categorized by age. The are listed below. The age distribution of for the given categories is 18% for under 26, 39% for 26-45, 31% for 46-65, and 12% for over 65. Test the claim that all ages have crash rates proportional to their driving rates (use alpha = .05).

A random sample of 24 groups of adults has a mean daily lodging cost of $233 and a standard deviation of $12.50. Is there enough evidence to reject the claim at α= 0.10? Assume the population is normally distributed.
Consider the following data for two independent random samples taken from two normal populations. What is the 90% confidence interval estimate of the difference between the two population means?
Are you doubtful of any of these data points? if so why does there show to be a linear relation between degree of stenosis and nuber of reactive nuclei?
Determine the mean and standard deviation of the data. What percentage of the data lies within one standard deviation of the mean value?
What is the probability of making a Type II error if the population mean is 24,000 miles?
Researchers wanted to determine if there is a difference in the mean credit card debt owed by males versus females. Using α = 0.10, is there a difference. (Show all six steps of hypothesis testing.)
When combining probabilities, to find the probability of one event AND another event, the separate probabilities should be
At the .05 significance level, can we conclude that the mean waiting time is less than 3 minutes?
A study of the amount of time it takes a mechanic to rebuild the transmission for a 1992 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours.
The number of runs with respect to the sample median is:
Utilizing Excel data analysis calculate t distribution also deduce the result. Study of variance is used to investigate if there is a difference in the mean mileage of the three cars.
