Question

Deliverable 02 – Worksheet Instructions: The following worksheet is shown to you by a student who is asking for help. Your job is to help the student walk through the problems by showing the student how to solve each problem in detail. You are expected to explain all of the steps in your own words. Key: · - This problem is an incorrect. Your job is to find the errors, correct the errors, and explain what they did wrong. ·
- This problem is partially finished. You must complete the problem by showing all steps while explaining yourself. · - This problem is blank. You must start from scratch and explain how you will approach the problem, how you solve it, and explain why you took each step. 1)
Assume that a randomly selected subject is given a bone density test. Those tests follow a standard normal distribution. Find the probability that the bone density score for this subject is between -1.93 and 2.37 Student’s answer: We first need to find the probability for each of these z-scores using Excel. For -1.93 the probability from the left is 0.0268, and for 2.37 the probability from the left is 0.9911. Continue the solution: Finish the problem giving step-by-step instructions and explanations. Mean = 0 ; Std = 1 P( -1.93>X X-1.645) = 1-P(Z0.8980)= Right side of the data = 0.5-0.31327 = 0.)
Manhole covers must be a minimum of 22 in. in diameter, but can be as much as 60 in. Men have shoulder widths that are normally distributed with a mean of 18.2 and a standard deviation of 2.09 in. Assume that a manhole cover is constructed with a diameter of 22 in. What percentage of men will fit into a manhole with this diameter? Student’s answer: We need to find the probability that men will fit into the manhole. The first step is to find the probability that the men’s shoulder is less than 22 inches. Continue the solution: Enter your step-by-step answer and explanations here.
