Consider Ho:µ = 45 versus H1: µ < 45. %D a. A random sample of 25 observations produced a sample mean of 41.6. Using a = 0.05, would you reject the null hypothesis? The population is known to be normally distributed witho = 8. b. Another random sample of 25 observations taken from the same population produced a sample mean of 43.3. Using a = 0.05, would you reject the null hypothesis? The population is known to be normally distributed with o 8.
