Consider Ho: M = 45 versus H₁: μ< 45. a. A random sample of 25 observations produced a sample mean of 41.4. Using a = 0.05, would you reject the null hypothesis? The population is known to be normally distributed with o = 9. 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 = 9.
