· A drug company is considering marketing a new local anesthetic. The effective time of the anesthetic the drug company is currently producing has a normal distribution with an average of 7.4 minutes with a standard devia- tion of 1.2 minutes. The chemistry of the new anesthetic is such that the effective time sho- uld be normal with the same standard devia- tion, but the mean effective time may be lo- wer. If it is lower, the drug company will market the new anesthetic; otherwise, they will continue to produce the older one. A sam- ple of size 36 results in a sample mean of 7.1. A hypothesis test will be done to help make the decision. Test hypothesis in level of significance = 0.10

/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 ...
