Key Concepts of Tests of Hypotheses on the Population Mean and Population Proportion.

Ben claims that the average midi-chlorians a jedi had in his time was 15,000 with a standard deviation of 1500. Luke doesn’t believe it and claims that it is lesser than that so tested his new set of Jedi students and found out that with 12 Jedi’s they had an average of 16,500 midi-chlorians. Test if the average midi-chlorians is less than 15,000. Use 1% level of significance.​
