Question 1175598: A genetic experiment with peas resulted in one sample of offspring that consisted of 431 green peas and 156 yellow peas.
a. Construct a 90% confidence interval to estimate of the percentage of yellow peas.
b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations?

Hi

a) p(yellow) 156/ 587 = .2657

b) Ho   p = .25 expectations
   Ha   p > .25


   z = .878
  P(z .878) = .81  
  90% confidence Interval. 
  .81 > .10 Fail to reject Ho
 Evidence supports the expectation that μ = .25

Wish You the Best in your Studies.
