Let n1equals100?, Upper X 1equals50?, n2equals100?, and Upper X2equals30. Complete parts? (a) and? (b) below. a. At the 0.01 levelof? significance, is there evidence of a significant differencebetween the two population? proportions?
a) Calculate the test? statistic, Upper Z Subscript STAT?, basedon the difference p1minusp2. The test? statistic, Upper Z SubscriptSTAT.
b) While either a standardized normal distribution table ortechnology may be used to calculate the? p-value, for this?exercise, use technology. Identify the value of the? p-value fromyour technology? output.
c. Construct a 95?% confidence interval estimate of thedifference between the two population proportions.
