The sample statistics from one ex having yellow pods. Find the value of the test statistic The value of the test statistic is (Round to two decimal places as needed.)

Solution

for proportion the test statistics is Z

Po= 0.25

P=147 / 510 =0.2882

Z = ( 0.2882 - 0.25 ) / srqt [(0.25*0.75) / 510]

Z = 0.0382 / 0.01917

Z = 1.99

the value of the test statistic is 1.99
