Use the Roll Verification Data 1) Create a Histogram for the Height data. Convert to feet only to do this.ex 5 feet 3inches is 5+3/12=5.25 2) Calculate the mean, median, standard deviation A Hypothesis test 3) Jed raises chickens. He says that the average chicken weight is 5.5 lbs. Test his claim. A simple random sample, looks like it's from a Normal distribution of Jed's chickens was collected with the following data in pounds: 3.4, 5.8, 6.0.4.2.5.7.7.1.6.3, 6.2.5.1,7.2 (you find...

The
heights of men are normal distributed, with a mean of 69.4 inches
and a standard deviation of 2.69 inches. The heights of adult women
are also normal distrubuted, but with a mean of 64.7 inches and a
standard deviation of 2.51 inches.

The height of an adult male has a mean of 70 inches and a standard deviation of 3 inches. Using the SD Rule approximately what percentage of men have heights between 64 and 76 inches? Give a percent, not a decimal QUESTION 3 The number of Matthew McConaughey movies that a typical person has seen has a mean of 4 movies and a standard deviation of 1 movie. The SD rules suggests that 99.7% of people have seen between and...
Adult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the height of a man with a z-score of 0.9 (to 2 decimal places) 71.52 Question 3. Points possible: 2 This is attempt 1 of 1. The mean amount of time it takes a kidney stone to pass is 15 days and the standard deviation is 4 days. Suppose that one individual is randomly chosen. Let X = time to pass the...
Suppose that height is normally distributed with a mean of 68 inches and a standard deviation of 4 inches. How many inches tall are the tallest 3% of people?
Adult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the z-score of a man 73.8 inches tall. (to 2 decimal places)
Given a mean of 62 and a standard deviation of 5, convert the random variables to Z-scores, then use a standard normal table below to find the probability. Pr[62 ≤ X ≤ 67] =
The mean height of males 20 years or older is 68 inches with a standard deviation of 3.5 inches. The mean height of females 20 years or older is 62 inches with a standard deviation of 2.5 inches. While a male has a height z-score of -1.3525, a female has a height z-score of 1.3525 5 How tall is he in inches? 26. How tall is she in inches? Test if the dataset: 7,22,16,5,46,40,21,22,33,90) is normally distributed by using Shapiro-Wilk...
2) Women's heights are normally distributed with a mean of 64.1 in, and a standard deviation of 2.5in. a) What percentage of adult women can fit through the doors on the Mark VI monorail (find the height of the doors on the Monorail in the chapter 5 notes)? b) Does the answer to part a mean that all women are under 6 ft tall?
