A genetic experiment with peas resulted in one sample of offspring that consisted of 416 green peas and 159 yellow peas.

a. Construct a 90% confidence interval to estimate of the percentage of yellow peas.

b. It was expected that25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not25%, do the results contradictexpectations?

a. Construct a 90% confidence interval. Express the percentages in decimal form.

nothing

nothing

(Round to three decimal places asneeded.)

b. Given that the percentage of offspring yellow peas is not25%, do the results contradictexpectations?

Yes, the confidence interval does not include0.25, so the true percentage could not equal25%

No, the confidence interval includes0.25, so the true percentage could easily equal25%
