Discussion:
Q1. Suppose you want to test the claim that population mean μ=3.5. Given a sample size of n=34 and a level of significance of α=0.01, when should you reject Ho?
Q2. Find the standardized test statistic t for a sample with n=15, sample mean=8.7, s=0.8, and α =0.05 if Ho is less than or equal to 8.4.
Q3. Find the standardized test statistic t for a sample with n=12, sample mean=20.6, s=2.1, and α=0.01 if Ha: population mean miu not equal to 21.1.
