In a study of the accuracy of fast food drive-through orders, Restaurant A had 207 accurate orders and 52 that were not accurate.a. Construct a 95% confidence interval estimate of the percentage of orders that are not accurate.b. Compare the results from part (a) to this 95% confidence interval for the percentage of orders that are not accurate at Restaurant B: 0.171< p < 0.281. What do you conclude?a. Construct a 95% confidence interval. Express the percentages in decimal form.|

Virginia wants to estimate the percentage of students who live more than three miles from the school. She wants to create a 95% confidence interval which has a margin of error of at most 5%. How many students should be polled to create the confidence interval? z0.10 z0.05 z0.025 z0.01 z0.005 1.282 1.645 1.960 2.326 2.576 Use the table of values above.
Refer to the accompanying data set and construct a 90% confidence interval estimate of the mean pulse rate of adult females; then do the same for adult males. Compare the results. Click the icon to view the pulse rates for adult females and adult males. Construct a 90% confidence interval of the mean pulse rate for adult females. | bpm<µ<| bpm (Round to one decimal place as needed.) Construct a 90% confidence interval of the mean pulse rate for adult males. |bpm<μ< bpm (Round to one decimal place as needed.) Compare the results. A. The confidence intervals overlap, so it appears that there is no difference in mean pulse rates between adult females and adult males. B. The confidence intervals do not overlap, so it appears that adult females have a higher mean pulse rate than adult males. C. The confidence intervals overlap, so it appears that adult males have a higher mean pulse rate than adult females. D. The confidence intervals do not overlap, so it appears that there is no…

A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their school
You are interested in finding a 90% confidence interval for the average commute that non-residential students have to their college. The data below show the number of commute miles for 14 randomly selected non-residential college students. Round answers to 3 decimal places where possible. 5 8 11 10 12 19 24 6 26 10 26 10 26 15 a. To compute the confidence interval use a distribution. b. With 90% confidence the population mean commute for non-residential college students is between and miles. c. If many groups of 14 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of commute miles and about percent will not contain the true population mean number of commute miles.
