a) Min Xian believes that the average COVID-19 cases for the age group 70 years
old+ is less than 250. Test the claim using a = 0.05.
b) Find 99% confidence interval of the means of age group 12 years old to 29 years
old.
c) On the other hand, Yi Hang want to investigate whether there is a difference
between mean COVID-19 cases in Klang Valley and Pulau Pinang for age group of
30 years old to 49 years old. Test the claim using a = 0.02.
d) Find 80% confidence interval of the means between age group 0 years old to 11
years old and age group 50 years old to 69 years old.
