genetic experiment with peas resulted in one sample of offspring that consisted of green peas and yellow peas. a. Construct a % 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 % confidence interval. Express the percentages in decimal form. nothingp nothing (Round to three decimal places as needed.) 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%

Complete Question

A genetic experiment with peas resulted in one sample of offspring that consisted of 432 green peas and 164 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?

The  95%  confidence interval is  

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

Step-by-step explanation:

From the question we are told that

  The total sample size is  

   The  number of  offspring that is yellow peas is

   The  number of  offspring that is green peas   is

The sample proportion for offspring that are yellow peas is mathematically evaluated as

Given the the  confidence level is  95% then the level of significance is mathematically represented as

The  critical value of   from the normal distribution table is  

Generally the margin of error is mathematically evaluated as

=>      

=>      

The  95%  confidence interval is mathematically represented as

=>  

=>  

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
