Reference no: EM13107299

1. 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?

2. 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.

3. 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.
