Answer 1

To estimate the population mean annual salary for head basketball coaches at college and universities playing NCAA Division 1 basketball, we can use the given sample data and calculate the mean salary.

Step-by-step explanation:

To estimate the population mean annual salary for head basketball coaches at college and universities playing NCAA Division 1 basketball, we can use the given sample data. The sample consists of the salaries of 10 basketball coaches. We'll calculate the mean salary by summing up all the salaries and dividing by the number of coaches:

1. 
   
3. Add up all the salaries: 2.3 + 0.6 + 2.3 + 2.6 + 2.1 + 1.3 + 1.5 + 1.5 + 0.2 + 0.4 = 14.8 million dollars
4. 
   
6. Divide the total by the number of coaches: 14.8 / 10 = 1.48 million dollars

Therefore, the estimated population mean annual salary for head basketball coaches at college and universities playing NCAA Division 1 basketball is 1.48 million dollars per year.

Answer 2

The estimated population mean annual salary for NCAA Division I head basketball coaches is calculated by adding the sample salaries and dividing by the total number of schools, resulting in 1.48 million dollars per year.

Step-by-step explanation:

To estimate the population mean annual salary for head basketball coaches at colleges and universities playing NCAA Division 1 basketball, we take the sample mean of the given salaries. First, we add up all the salaries from the 10 schools:

2.3 + 0.6 + 2.3 + 2.6 + 2.1 + 1.3 + 1.5 + 1.5 + 0.2 + 0.4 = 14.8 million dollars

Then we divide the total by the number of schools to find the mean:

14.8 million dollars / 10 schools = 1.48 million dollars per year

Therefore, the estimated population mean annual salary for head basketball coaches in NCAA Division I is 1.48 million dollars per year.
