It is known that the average age of someone in the NFL is 26.2 years old. Suppose we take a sample of 15 athletes and find that the average age is 26.8 years old with a sample standard deviation of 3.22 years. We are interested in testing if the average age of NFL players is increasing. Using the sample of 15 players, what would the 95% confidence interval be for the population mean? What are the null and alternative hypotheses?...

The mean age of random university, College students in a previous term was 26.6 years old. An instructor thinks the mean age for online students is older than 26.6. She randomly surveys 60 online students and finds that the sample mean is 29.6 with a standard deviation of 2.1. Conduct a hypothesis test at the 5% level. Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general,...

The university finance department wants to know if the average age of students at their university is greater than the average for other universities. A random sample of student records is taken from the own university (population 1) and a random selection of student ages from other three universities are taken (population 2). A significance level of 0.05 is chosen. The null and alternative hypotheses are: ?0: ??: The samples are selected, and the results are: ?1 = 28,7 ????? ?1...

7. A group of university students are interested in comparing the average age of cars owned by students and the average age of cars owned by faculty. They randomly selected 25 cars that are own by students and 20 cars that are owned by faculty. The average age and standard deviation obtained from the students’ cars are 6.78 years and 5.21 years, respectively. The sample of faculty cars produced a mean and a standard deviation of 5.86 years, and 2.72....
