2. The following is a set of hypotheses, with some information from one or more samples. 130, with a p=0.16 and n = 100 with a p2= 0.21. Calculate the standard error of p1 - p2, check the conditions, and find the value of the standardized z-test statistic. Write the equations with the numbers filled in for full credit. Round your answers to three places. (16 points) Test Ho: p1 = p2 vs Ha: pi < p2 when the samples have n = SE = Check Conditions: z-statistic: p-value: Decision? val is
