A local five-star restaurant asks its patrons to fill out a quick satisfaction survey (is the patron satisfied or not) after theirmeal, and the restaurant claims that their satisfaction rating is 84%. Jennie, a food critic, would like to test this. She takes asample of 129 patrons, and gets a 79.1% sample satisfaction rating.(a) Create an 80% confidence interval for the restaurant's true satisfaction rating. (Provide answers in decimal form, notpercentage. Thus, 77.3% becomes 0.773. Round your answers to four decimal places, if needed.)(b) Based on this confidence interval, should Jennie reject the null hypothesis that the satisfaction rating is 84%?O Since the interval contains 84%, Jennie should reject the null hypothesis at a = 0.2.O Since the interval does not contain 84%, Jennie should not reject the null hypothesis at a = 0.2.O Since the interval contains 84%, Jennie should not reject the null hypothesis at a = 0.2.O Since the interval does not contain 84%, Jennie should reject the null hypothesis at a = 0.2.

The random variable satisfaction rating follows normal distribution. The sample size is 129. The…

Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)
GSS 2018 respondents were asked to rate their level of agreement to the statement, “Differences in income in America are too large.” Responses were measured on a 5-point scale: 1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree. Strong Democrats had an average score of 1.69 (s = 1.04, N = 86) while strong Republicans had an average score of 2.11 (s = 1.05, N = 67). The estimated standard error of the difference between meansis 0.17. What is the appropriate test statistic? Why? Test the null hypothesis with a one-tailed test (strong Democrats are more likely to agree with the statement than strong Republicans); α = .05. What do you conclude about the difference in attitudes for these two political groups? If you conducted a two-tailed test with α = .05, would your decision have been different?

Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating. Is there significant evidence at the 5% level that the mean rating is greater than 3.5 (a neutral rating)?
