You obtain a sample from the second population with 395 successes and 44 failures. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value The p-value is...

Explanation / Answer

p1 = 82/561 =0.1462

p´2 = 44 / 395 = 0.1114

p = (82+44) / ( 561+395) = 0.1318

Z = ( 0.1462 - 0.1114) / SRQT [ 0.1318*0.8682*(1/561+1/395) ]

Z = 1.566

p value : 0.0582
