Question
1. 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 500 peas with 153 of them having yellow pods. Find the value of the test statistic.
2. Assume that the significance level is alpha equals 0.01. Use the given information to find the P-value and the critical value(s).The test statistic of z equals 1.02 is obtained when testing the claim that p greater than 0.6

Explanation / Answer
Q1.
Test Statistic
No. Of Success chances Observed (x)=153
Number of objects in a sample provided(n)=500
No. Of Success Rate ( P )= x/n = 0.306
Success Probability ( Po )=0.25
Failure Probability ( Qo) = 0.75
we use Test Statistic (Z) for Single Proportion = P-Po/Sqrt(PoQo/n)
Zo=0.306-0.25/(Sqrt(0.1875)/500)
Zo =2.8918
