Let n1equals100, Upper X 1equals50, n2equals100, and Upper X
2equals30. Complete parts (a) and (b) below. a. At the 0.01 level
of significance, is there evidence of a significant difference
between the two population proportions?
a) Calculate the test statistic, Upper Z Subscript STAT, based
on the difference p1minusp2. The test statistic, Upper Z Subscript
STAT.
b) While either a standardized normal distribution table or
technology may be used to calculate the p-value, for this
exercise, use technology. Identify the...
