An automobile manufacturer introduces a new model that averages 26 miles pergallon in the city. A person who plans to purchase one of these new cars wrote themanufacturer for the details of the tests, and found out that the standard deviation is2 miles per gallon. Assume that in-city mileage is approximately normally distributed.For each of the questions below make sure to show your work. Round any z-scorecalculated to two decimal places to find your result.1. What percent of these vehicles have a fuel consumption of 22 to 30 miles pergallon?2. The manufacturer wants to know what percent of vehicles have a fuelconsumption less than 23 miles per gallon.3. Find the fuel consumption for the 90th percentile. Round to one decimalplace.

Given: μ = 26 σ = 2 Formula Used: Z-score = X-μσ X = μ+Zσ

INSTRUCTION: Perform an appropriate statistical test using the dataset (Sheet name: Cholesterol) if a researcher would like to determine if there is a significant difference in the "Cholesterol" level before ("Pre") and after ("Post") the treatment or therapy? Dataset for this can be retrieved on the given Excel. 1. What is the computed p-value for the given data on the "Cholesterol" level before ("Pre") and after ("Post") the treatment or therapy? Round it off to two decimal places. Then, answer (YES or NO) if there is a significant difference in the "Cholesterol" level before ("Pre") and after ("Post") the treatment or therapy? 2. What is the computed Mean of "Post" on the given data for Cholesterol? Round it off to two decimal places. 3. What is the computed Standard Deviation of "Pre" on the given data for Cholesterol? Round it off to two decimal places.
A set of data had a sample mean of 42.0 and a sample standard deviation of 11.0. What is the coefficient of variation (CV), expressed as a percentage, for this set of data? Round your answer to two decimal places. Do not include the percent sign. Your Answer:
Suppose you have already calculated the mean, the average deviation, and the standard deviation of the weights in pounds of 20 third-graders. a. if these weights were converted to kilograms and the mean and the average deviation were once again calculated, would the second average deviation be (numerically) less than, greater than, or equal to the first average deviation? Explain your answer. b. If the standard deviation of these weights were calculated in kilograms, would it be (numerically) less than, greater than, or equal to the first standard deviation? Explain your answer
