Question

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

490peas with 101of them having yellow pods. Find the value of the test statistic.The value of the test statistic is ?

Answer 1

p = 101/490 = 0.20612245-

1 - p = 0.79387+

standard deviation = sqrt( p(1-p)/N) = 0.018274234-

test stat is (0.25 - 0.20612245) / standard deviation = 2.401062

reject null hypothesis

stat evidence shows the population proportion is not 25%
