Check those assumptions: 1. np = 1539 of which is 2 v of 10 2. n(1 - p) = 361 of which is 2 v of 10 3. N = 1000000 of which is 2 v of If no N is given in the problem, use 1000000 N: NAME THE PROCEDURE The conditions are met to use a 1-Proportion Z-Test VY of . T: TEST STATISTIC The symbol and value of the random variable on this problem are as follows: Leave this answer as a fraction. The formula set up of the test statistic is as follows. : (Leave any values that were given as fractions as fractions) p - P P(1-P) 0.81 OF . (1 - 0.8 1 0- ) ) / 1900 of ) Final answer for the test statistic from technology. Round to 2 decimal places: Z = O: OBTAIN THE P-VALUE Report to 4 decimal places. It is possible when rounded that a p-value is 0.0000 P-value = M: MAKE A DECISION Since the p-value s vv of we reject H vv of
