/transcript 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. The accompanying table shows this data. In writing an article about call center working conditions, a reporter has claimed that the average tenure is no more than two years. Formulate and test a hypothesis using these data to determine if this claim can be disputed. Use a level of significance of 0.05. Click the icon to view the call center data. Is there sufficient evidence at the 0.05 level of significance that the average tenure is no more than two years? Determine the null hypothesis, Ho, and the alternative hypothesis, H₁. Ho ...

3. Overa long period of time, it was found that the time taken for the standard physical task is normally distributed with mean 50 seconds, and variance 100 sec². A sample of 75 workers were given a special and unusual diet for three weeks before they were observed performing said standard physical task. The mean time taken by this sample is 46 seconds. Is this significant evidence that the special diet has made a difference in their performance. Use a 5%level of significance.
