In this question you will look more closely at the average at which people die from this disease. NSW health claims that the average at which people die from this disease is 26 years old. However, according to our data the average age people die is younger than 26 and we wish to prove this. To do this you are to carry out a hypothesis test at a 5% significant level to determine if the average age at which the people die from this age is lower than 26. The calculated p-values for your data sets are given in the table 8 (Q4 Data Set) below: Group 1 2 3 5 6 p value 0.061596 0.000839 0.000299 0.035705 0.170057 0.032982 0.002487 You will not need Excel work for this question. a) State the null and alternative hypotheses. b) Draw a diagram and show the p-value and rejection zone. (Select the p-value corresponding to your group from the above table) [1] [2] c) What is the decision about your hypothesis statement, at a significance level of 5%? Clearly justify your answer using appropriate numerical values. [1] d) What do you conclude about the mean age at which the people die from this disease?
