Students conduct an experiment in lab where theyplace a speaker playing a constant 100 Hz tone on acart and record the frequency of the sound recordedby a microphone when the cart moves at differentspeeds towards the microphone. They want to see ifthere is a relationship between the speed the cartmoves and the frequency of the sound detected by themicrowave. Below is the data they collected from thisexperiment.

QUESTION 8 Mixed Practice Read through the problem below. Then, identify the problem type by stating whether the problem is a "regular" problem or a "CLT" problem. Then identify the direction by stating whether it is a “forwards" or a "backwards" problem. Then, solve the problem. Round standard error vlaues to the nearest thousandth and z-scores to the nearest hundredth whenever necessary. According to values collected from gasbuddy.com in the spring of 2016, the mean price for a gallon of gas in Oneida County was $2.12, with a standard deviation of $0.06. Madina examines a SRS of 32 gas stations, and finds her sample has a mean in the 97th percentile. What was the mean price of gas in Madina's sample, to the nearest cent?

Question 20: A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y).The results of the regression were:y=a+bx b=-0.656 a=27.975 r2=0.426409 r=-0.653 Use this to predict the number of situps a person who watches 6 hours of TV can do. Round to one decimal place.
Question 6 of 14 Identify the reasons the following statements are incorrect. Not all reasons will be used. Researchers found that the correlation between the number of vacation days available per year and the employees' years of employment is r = 0.65 days. The correlation between the average lifespans of animals and the animals' species is r = -0.78. The number of steps people take while walking and the distance they walk are highly correlated (r = 1.12). The correlation between average gas mileage in miles per gallon and average highway speeds in miles per hour differs from the correlation between average gas mileage in miles per gallon and average highway speeds in kilometers per hour. Answer Bank Correlation should be between -1 and 1. Correlation should depend on units. Correlation should be greater than 0. Correlation should not depend on units. One of the variables should be categorical. Both variables should be numerical.
