Use the population of ages {56, 49, 58, 46} of the four U.S. presidents (Lincoln, Garfield, McKinley, Kennedy) when they were assassinated in office. Assume that random samples of size n = 2 are selected with replacement. 1. List the 16 different samples. For example, the samples for age 56 would be 56, 56 56, 49 56, 58 56, 46. 2. After listing all 16 samples, find the mean of each sample, then construct a table representing the sampling distribution...

6. (8 points) One histogram shows the distribution of ages of 300 pennies. The other two graphs show distributions of means from random samples taken from the same population of pennies. One histogram shows means based on samples of 5 pennies, and another shows means based on samples of 100 pennies. Each graph with means was done with many repetitions. Which distribution is which, and how do you know? Aeuency 20 IS AGE AGE C F.equency Population: Sample size 5:...

Imagine that you are doing an exhaustive study on the children in all of the elementary schools in your school district. You are particularly interested in how much time children spend doing active play on weekends. You find that for this population of 2,431 children, the average number of minutes spent doing active play on weekends is μ = 87.85, with a standard deviation of ơ-118.1. You select a random sample of 25 children of elementary school age in this...
