Suppose that air temperature in crown is normally distributed. A random sample of 17 readings gave a mean of 22.5 and a variance temperature of 3.7. a) Calculate a 95% lower confidence bound for the population mean. i) Write the formula. (5 points) ii) Find the necessary table value. (5 points) iii) Calculate lower bound. (15 points) iv) Interpret your bound. (10 points) b) Do you think that the mean temperature is greater than 20? Why? / Why not? Use your lower bound (part a) to draw conclusion. (15 points)
