A sample of 36 observations is selected from a normal population. The sample mean is 21, and the population standard deviation is 5. Conduct the following test of hypothesis using the .05 significance level.H0: μ ≤ 20H1: μ > 20
A sample of 36 observations is selected from a normal population
1. A sample of 36 observations is selected from a normal population. The sample mean is 21 , and the population standards deviation is 5 . Conduct a test of hypothesis using the 0.05 significance level. Null hypothesis =20 . Alternate = ?2. A sample of 81 observations is taken from normal population with a standard deviation of 5 . The sample mean is 40 . Determine the 95 %confidence interval for the population.3. Given the following sample observations which...
