The claim is that the proportion of peas with yellow pods is equal to 0.25 (or 25%). The sample statistics from one experiment include 470 peas with 96 of them having yellow pods. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)

Answers

Answer:

Given that:

The claim is that the proportion of peas with yellow pods is equal to 0.25​ . The sample statistics from one experiment include 470 peas with 96 of them having yellow pods. Find the value of the test statistic.

Ho: p=0.25

H:p +0.25

Sample proportion= 96/470 =0.204

Test Statistic:

z=(0.204-0.25)/sqrt[(0.25*0.75)/470]

z = -0.046/0.019973

Z =-2.31
