The National Collegiate Athletic Association (NCAA) reported that the mean number of hours spent per week on coaching and recruiting by college football assistant coaches during the season was 70. A random sample of 50 assistant coaches showed the sam- ple mean to be 68.6 hours, with a standard deviation of 8.2 hours.
a. Using the sample data, construct a 99 percent confidence interval for the population mean.b. Does the 99 percent confidence interval include the value suggested by the NCAA? Interpret this result.c. Suppose you decided to switch from a 99 to a 95 percent confidence interval. Without performing any calculations, will the interval increase, decrease, or stay the same? Which f the values in the formula will change?
A precision parts manufacturer produces bolts for use in military aircraft. The specifications for bolt length are 37.50 ± 0.25 cm. The company has established an -chart and an R-chart using samples of size five.
Why is it important that a sample be random and representative when conducting hypothesis testing?
