The data shows the number of years that 30 employees worked for an insurance company before retirement. is the population mean for the number of years worked, and % of the employees worked for the company for at least 10 years. (round off your answers to the nearest integer.)

the table of the data is not given, therefore, i can only with the concept.

i can tell you how to solve each question and you apply using the numbers/data you have.

1- getting the mean:

mean is the average number of years that each worker worked. therefore, to get the mean, all you have to do is find the total number of years worked and divide it by the total number of workers.

2- getting the percentage:

we want to get the percentage of the workers who worked more than 10 years. to do so, count the number of workers who worked 10 years or more and divide it by the total number of workers. finally, multiply the quotient by 100 to get the percentage.

hope this : )
