Twenty different statistics students are randomly selected. For each of them, their body temperature
(°C)
is measured and their head circumference (cm) is measured.
a. For this sample of paired data, what does r represent, and what does
ρ
represent?
b. Without doing any research or calculations, estimate the value of r.
c. Does r change if body temperatures are converted to Fahrenheit degrees?

Part 1
a. Choose the correct answer below.
A.
r is a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students, and
ρ
is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data.
B.
r is a statistic that represents the proportion of the variation in head circumference that can be explained by variation in body temperature, and
ρ
is a parameter that represents…

- Mr. John operates a medium size business that sells tires. He buys most of his tires from a company that is located in South America. Mr. John believes that he is stocking too much tires so he decided to look into the situation. He wants to use the Economic Order Quantity (EOQ) model to manage his stock of tires. In order to use this model, he must first of all forecast the annual demand for his tires. Using a numerical example, demonstrate to Mr. John how he can use the manual trend projection method of forecasting to forecast demand for the next two years.arrow_forwardA large school district is reevaluating its teachers' salaries.

- (PLEASE HELP WITH 1 AND 2) The National Occupant Protection Use Survey (NOPUS) was conducted to provide probability-based data on motorcycle helmet use in the United States. The survey was conducted by sending observers to randomly selected roadway sites where they collected data on motorcycle helmet use, including the number of motorcyclists wearing a Department of Transportation (DOT)-compliant helmet (National Highway Traffic Safety Administration website, January 7, 2010). Sample data consistent with the most recent NOPUS are shown below. Answer questions 8 -10.
