To be selected to serve on a jury, one must be on the list of registered voters in the province and have reached the age of majority . The average age for registered voters in a province is 39.7 years, with a standard deviation of 11.8 years.
A
1) What shape do you think this distribution has? Explain.
2) Can you use Table Z to find the probability that a randomly chosen juror is at least 50 years old? Explain.
B If we were to take a random sample of 50 jurors, will the assumptions for the central limit theorem hold? Explain in the . context of the question
1) Is the independence assumption met? Check both the randomization condition and 10% condition, clearly and in context.
2) ls the normal population assumption met? Explain in context.
3) Is the sample size assumption met? Check the large enough sample condition.
4) For the sample of 50, what would be the mean age of jurors?
5) For the sample of 50 jurors, what is the standard deviation for their age?Show your work.
6) Using the 68-95-99.7 rule, there is a 0.95 probability that the average juror age for the sample of 50 falls between______to______
