A corporation produces packages of paper clips. The number of clips per package varies, as indicated below for a sample of 20 packages. 53 47 51 52 47 49 51 50 48 53 52 50 51 48 52 47 47 52 50 51 Create a probability density function. What is the probability that a randomly chosen package contains between 47 and 52 clips (inclusive) per package? Please specify your answer in decimal terms and round your answer to the nearest hundredth (e.g., enter 12 percent as 0.12).
Both 47 and 52 inclusive

A cognitive retraining clinic assists outpatient victims of head injury, anoxia, or other conditions that result in cognitive impairment. Each incoming patient is evaluated to establish an appropriate treatment program and estimated length of stay. To see if the evaluation teams are consistent, 12 randomly chosen patients are separately evaluated by two expert teams (A and B) as shown.

A package delivery service adopted a new dispatching system to try to reduce the total mileage required by its truck fleet to make deliveries. The new system would be worth the cost if it reduced the fleet mileage by more than 10% from its current level of 2200 miles per day. The miles required for each of the 66 days under a trial of the new system are recorded in column 1 of the Excel data file named “Package Delivery”....

Calculate the mean, median, and standard deviation for the total number of candies (per bag). Construct a histogram of the total number of candies (per bag). Use the z-score method to identify any potential outliers and outliers. Assume the total number of candies is normally distributed, calculate the probability that a randomly sampled bag has at least 55 candies in a bag. If a random sample of 50 bags is selected, find the probability that the mean number of candies...
