A genetic experiment with peas resulted in one sample of offspring that consisted of 426 green peas and 156 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 genetic experiment with peas resulted in one sample of offspring that consisted of 412 green peas and 151 yellow peas. a. Construct a 95% confidence interval to estimate of the percentage of yellow peas by 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?

2)   A random sample of 120 students at a high school was asked whether they would ask their father or mother for help with a homework assignment in science. A second random sample of 150 different students was asked the same question for an assignment in history. Fifty-four students in the first sample and 72 students in the second sample replied that they turned to their mother rather than their father for help. Construct a 99% confidence interval for the difference of the two proportions and express it as   .   (Round both numbers to the 4th decimal plac

A genetic experiment with peas resulted in one sample of offspring that consisted of 443 green peas and 167 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?

In a poll of 26 randomly selected students showed that 24.6% of the respondents believe in global warming. Based on the sample results, the margin of error E that corresponds to a 80% confidence level is equal to: O a. 0.17 O b. 0.14 O c. 0.11 O d. 0.22

A survey was conducted to determine what percentage of college seniors would have chosen to attend a differentcollege if they had known then what they know now. In a random sample of 100 seniors, 34 percent indicated thatthey would have attended a different college. A 90 percent confidence interval for the percentage of all seniors whowould have attended a different college is

Suppose that in a recent poll, 550 of the 915 randomly selected U.S. adults agreed with the statement “social media sites like Facebook and Twitter do more to divide the country” (as opposed to unite the country, or neither). a. Use this information to construct a 90% confidence interval.

In a poll of 7 randomly selected students showed that 31.3 % of the respondents believe in global warming. Based on the sample results, the margin of error E that corresponds to a 95% confidence level is equal to: O a. 0.45 O b. 0.34 O c. 0.29 O d. 0.22

According to some car loan statistics, 44% of Americans are relying on an auto loan to pay for their cars. Assuming this finding to be based on a simple random sample of 1500 Americans, construct and interpret the 95% confidence interval for the population proportion of Americans who have a car loan.

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned.   Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.”    Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations.   1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
