NEED ASAP

part 1) It is not clear if the two data sets x1 = {23, 28, 22, 23, 25, 27, 24, 29} and x2= {45, 23, 32, 24, 19, 33, 19, 29} have a significant difference. Test the hypothesis µ1 = µ2 against the alternative hypothesis µ1 = µ2. Find the critical region corresponding to 95% confidence. (Do not assume anything about σ1 or σ2.)

Say you survey 500 people in a certain community to see how many own a shed. Of the 500, you find that x-many say they do own a shed, where x = 363

------------------------------------------------------------------------------

Part 2)

Find the 98% confidence interval for the true population proportion p of people who own a shed
