Use Toronto as population 1 and Montreal as population 2: You are interested in repeat buying behaviour. In your Toronto location, 95 of 207 customers made a second purchase within one week of the first; in Montreal 44 out of 81 made a second purchase within a week.

a.) What is the lower limit of the interval (to at least three decimals)?

b.) What formula should be used to calculate the p-value, if doing the calculation without a tool? (Here concentrate the on the structure. CDF refers to whichever distribution you are using: norm.s.dist, t.dist, etc.)

c.) What is the correct conclusion? (reject the null, accept the null, or do not reject the null)

d.) What is the correct null hypothesis?

e.) What is D0?

f.) What is the value of the test statistic (i.e., z, t, chi-square, F, etc.--depending on the test/distribution you are using)? Give your answer to at least three decimal places.

g.) What is the upper limit of the interval (to at least three decimals)?

h.) What type of test is this?

i.)What is the point estimate for the difference between population proportions (to at least three decimal places)?

j.) Which distribution is used for analyzing this situation?
