Suppose that you are an elementary school teacher and you are evaluating the reading levels of your students. You find an individual that reads 42.5 word per minute. You do some research and determine that the reading rates for their grade level are normally distributed with a mean of 90 words per minute and a standard deviation of 25 words per minute.

a. At what percentile is the child's reading level (round final answer to one decimal place).

b. Create a graph with a normal curve that illustrates the problem.

For the graph do NOT make an empirical rule graph, just include the mean and the mark off the area that corresponds to the student's percentile. There is a Normal Distribution Graph generator linked in the resources area. Upload file containing your graph below. Choose FileNo file chosen

c. Make an argument to the parents of the child for the need for remediation. Structure your essay as follows:

  1. A basic explanation of the normal distribution
  2. Why the normal distribution might apply to this situation
  3. Describe the specific normal distribution for this situation (give the mean and standard deviation)
  4. Interpret the answer to part a. including a definition of percentile.
  5. Explain how the graph created in part b. represents the child's reading level.
  6. Use the answers to parts a. and b. to emphasize the gravity of the situation.
  7. Give a suggested course of action.

Consider this scenario: You are in charge of a manufacturing facility that produces an automotive part (steel shaft for the gearbox) with an acceptable dimension of 2.5±0.05 inches in diameter. Note that, the most desirable product is one with diameter of exactly 2.5 inches. Two vendors are trying to sell you their machines for the shaft-machining task. You have to select a vendor. You asked both vendors to supply data on the machining accuracy of their machines for the given...

Sheila's doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if the glucose level is above 140 miligrams per deciliter (mg/dl) one hour after having a sugary drink. Sheila's measured glucose level one hour after the sugary drink varies according to the Normal distribution with μμ =...

As a part of preparation for this week test, let’s practice with another case related to the Normal distribution. Assign your numbers for mean μ and standard deviation σ. Then select a number “A” below mean μ, and a number “B” above mean μ. Use Appendix Table for the Normal Distribution to find probability that x is between A and B: P (A < x < B). Here are steps to follow: convert A to z score (let’s call it...
