2. Suppose you want to test the claim that population mean miu=3.5. Given a sample size of n=34 and a level of significance of alpha=0.01, when should you reject Ho?
3. Find the standardized test statistic t for a sample with n=15, sample mean=8.7, s=0.8, and alpha =0.05 if Ho is less than or equal to 8.4.
4. Find the standardized test statistic t for a sample with n=12, sample mean=20.6, s=2.1, and alpha =0.01 if Ha: population mean miu not equal to 21.1.
The solution provides step by step method for the calculation of test statistic for population mean . Formula for the calculation and Interpretations of the results are also included. Interactive excel sheet is included. The user can edit the inputs and obtain the complete results for a new set of data.
