A genetic experiment with peas resulted in one sample of offspring that consisted of 407 green peas and 153 yellow peas. a. Construct a 90​% 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 90​% 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?

A genetic experiment with peas resulted in one sample of offspring that consisted of 432 green peas and 172 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 recent Gallup Poll interviewed a random sample of 1523 adults. Of these, 868 bought a lottery ticket in the past year. The same Gallup Poll asked its 1523 adult respondents and also 501 teens (ages 13 to 17) whether they generally approved of legal gambling: 63% of adults and 52% of teens said yes. The margin of error for a 95% confidence statement about teens would be a. greater than for adults, because the teen sample is smaller.b. less than for adults, because the teen sample is smaller.c. less than for adults, because there are fewer teens in the population.d. the same as for adults, because they both come from the same sample survey.e. Can't say, because it depends on what percent of each population was in the sample.

A genetic experiment with peas resulted in one sample of offspring that consisted of 429 green peas and 169 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?

In a study investigating the difference in food preferences between men and women, researchers asked subjects to indicate whether they liked or disliked certain foods. One question was about liking cabbage. Twenty percent of a sample of 75 men liked cabbage, while 41% of a sample of 100 women indicated that they liked cabbage. Provide two confidence intervals, one for the proportion of men who like cabbage and one for the proportion of women who like cabbage. Use a 95% confidence level. State whether or not the populations are different and explain how you know this.

In a survey of 3116 adults aged 57 through 85​ years, it was found that 86.2​% of them used at least one prescription medication. Complete parts​ (a) through​ (c) below. a. How many of the 3116 subjects used at least one prescription​ medication? b. Construct a​ 90% confidence interval estimate of the percentage of adults aged 57 through 85 years who use at least one prescription medication. c. What do the results tell us about the proportion of college students who use at least one prescription​ medication?     A. The results tell us that there is a​ 90% probability that the true proportion of college students who use at least one prescription medication is in the interval found in part​ (b).   B. The results tell us​ that, with​ 90% confidence, the probability that a college student uses at least one prescription medication is in the interval found in part​ (b).   C. The results tell us​ that, with​ 90% confidence, the true proportion of college students who use at…
