Hypothesis Testing Question: 2017 Paper 2 Question 7
Hypothesis Testing Question: 2018 Paper 2 Question 5
(i) A sample of at least 30 should be taken, so that sample size is large enough for the mean time to fail of the fans to be approximated to that of a normal distribution by Central Limit Theorem.
(ii) Test Ho: µ = 65000 against H1: µ < 65000
µ = population mean time to fail of fan
Ho = null hypothesis
H1 = alternative hypothesis
