Question

A genetic experiment with peas resulted in one sample of offspring that consisted of 445 green peas and 164 yellow peas.

a. Construct a 95% confidence interval to estimate the percentage of yellow peas.

b. Based on the confidence interval, do the results of the experiment appear to contradict the expectation that 25% of the offspring peas would be yellow?

A genetic experiment with peas resulted in one sample of offspring that consisted of
445 green peas and 164 yellow peas.
a. Construct a 95% confidence interval to estimate of the percentage of yellow peas.
b. Based on the confidence interval, do the results of the experiment appear to
contradict the expectation that 25% of the offspring peas would be yellow?
a. Construct a 95% confidence interval. Express the percentages in decimal form.
(Round to three decimal places as needed.)
<p<
b. Based on the confidence interval, do the results of the experiment appear to
contradict the expectation that 25% of the offspring peas would be yellow?
Yes, the confidence interval does not include 0.25, so the true percentage could
not equal 25%
O No, the confidence interval includes 0.25, so the true percentage could easily
equal 25%

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
