Call centers typically have high turnover. The director of human resources for a large bank has compiled data on about 70 former employees at one of the bank’s call centers in the Excel file Call Center Data . In writing an article about call center working conditions, a reporter has claimed that the average tenure is no more than two years.

As you formulate and test a hypothesis using these data, what is the value of the t Test Statistic?

Solution

T value is equal to = xbar - mean / sigma / srqt (n)

suppose that xbar is 2 years ( because you dont give that data)

suppose sigma = 0.2

mean = 2

T = (2 - 2) / ( 0.2 /srqt (70) )

T = 0
