- The manager of a fleet of automobiles is testing two brands of radial tires and assigns one tire of each brand at random to the two rear wheels of eight cars and runs the cars until the tires wear out. The data (in kilometers) follow.

Measuring the amount of body fat a person carries is one way to monitor weight control progress, but measuring it accurately involves either expensive X-ray equipment or a pool in which to dunk the subject. Instead body mass index (BMI) is often used as a proxy for body fat because it is easy to measure: BMI = mass(kg)/(height(m))² = 703 mass(lb)/(height(in))². In a study of 15 men at TXST, both BMI and body fat were measured. Researchers imported the data into statistical software for analysis. A few values are missing from the output. Complete the table by filling in the missing values.

EMS sessions consisted of 30 contractions (4-second duration, 85 Hz) and were carried out three times per week for three weeks on 17 ice hockey players. The 10-meter skating performance test showed a standard deviation of 0.90 seconds. Is there strong evidence to conclude that the standard deviation of performance time exceeds the historical value of 0.75 seconds? Use a = 0.05.arrow_forward

Any overfilling or underfilling results in the shutdown and readjustment of the machine. A sample of 20 bottles is selected, and the sample shows an average filling volume of 7.5 ounces.

Of the 200 seeds that were planted, only 180 germinated. 95% confidence interval for the true proportion of seeds that germinate based on this sample is (85.8%, 94.2%).
