Question

A genetic experiment with peas resulted in one sample of offspring that consisted of 413 green peas and 157 yellow peas.

 a. Construct a 95% 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 95% confidence interval. Express the percentages in decimal form.

 b. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? 

No, the confidence interval includes 0.25, so the true percentage could easily equal 25% 

Yes, the confidence interval does not include 0.25, so the true percentage could not equal 25%

Answer 1
