A large online retailer places packed and ready-to-be-shipped boxes in a line on a conveyor belt. A sample of boxes will be used to estimate the mean weight of boxes shipped on a given day. One proposed method for selecting the sample is as follows: ⚫ Generate a random integer from 1 to 20. . Use that integer to select an initial box from the first 20 boxes in line on the conveyor belt. • Select every 25th box that follows the initial box on the conveyor belt for the rest of the day. Which of the following best describes the proposed sampling method? (A) Stratified random sample, stratified by time of day (B) Cluster sample, with times of day as clusters (C) Cluster sample, with box weights as clusters (D) Systematic random sample (E) Convenience sample

Florida State University has 14 statistics classes scheduled for its Summer 2013 term. One class has space available for 30 students, eight classes have space for 60 students, one class has space for 70 students, and four classes have space for 100 students.    Find the mean of X (Round to 2 decimal places)

The weights of all the turkeys sold in Fairfax County in 2020 were recorded in the data set “Fairfax Turkey Weights” found in the histogram. The weights are presented in pounds. There are 235,428 turkeys in this population. Calculate the probability that, in a random sample of eight turkeys, the mean weight is between 17 and 20 pounds. First, draw a picture with the rounded mean and values labeled and the shaded area representing the desired probability. Next, take a picture of your hand drawn sketch and upload it (if you do not have this technology, you may use any other method (i.e. Microsoft paint) to sketch the image). Then, complete this part by standardizing and using the Standard Normal Table to obtain this probability. Show your work “by hand”.

List three types of samples and explain it.

Consider a sample with data values of 26, 24, 22, 18, 32, 34, 29, and 24. Compute the  percentiles (to 2 decimal, if decimals are necessary). 20th  25th 65th 75th
