We are now going to use Excel to test a hypothesis based on one given sample. We would like to know if the average cholesterol level of patients in intensive care is equal to 200 and for that reason we collect cholesterol level of 20 random people from various intensive care units. I Cholesterol level 154,168,134,201,208,220,225,228,201,207,168,211,203,254,268,198,298,135,154,189 We put our data in column A. In Cells A3-A22 we type our data and in cell Al we type Cholesterol.

Use another random decimal fraction generator at Random.org, linked here, to generate a list of ten two-digit random numbers between 10 and 30. Calculate the z-score of the median of the data set. Set 1: 13, 14, 20, 21, 22, 24, 25, 26, 27, 30 What does the z-score of the data set median just above tell you about the shape of the distribution? How do you know this? If you were to take repeated random samples of n =...

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...

Excel is allowed!
For this lab, we will create a spreadsheet that allows somebody to type in a loan amount, interest rate, and length of the loan in years. The spreadsheet will then calculate the monthly payment required and the actual amount paid on the loan. First, setup your spreadsheet: • In Cell A1, put the label Loan Amount:. The corresponding value would be input in Cell B1. • In Cell A2, put the label Interest Rate:. The corresponding value...

Part B: Sampling and Random Variable You already have ten marked pennies (ones with numbers from Part A) and 15 unmarked pennies. Thought experiment: Throw them all in a jar and shake. Without looking, pull three out and record how many of them are marked (have a number). You will get 0, 1, 2, or 3 marked coins. How many different samples of 3 pennies out of 25 can you get? (Order doesn’t matter.) Answer: 2,300 Show why 2,300 is...
