Q3. a) Discuss the general procedure for hypothesis testing. b) The average weight of pine trees in a forest is normally distributed with mean 53.45 and a standard deviation of 2.51. A sample of 20 pine trees are taken from the forest and their mean is recorded 64.85. Test the hypothesis that the average weight is less than 2.51. Using Z, = 2.83.
