yellow peas.a. Construct a

9090 %

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?

a. Construct a

9090 %

confidence interval. Express the percentages in decimal form.
