In Exercises 5–8, use the relatively small number of given bootstrap samples to construct the confidence interval.
8. Cell Phone Radiation Here is a sample of measured radiation emissions (cW/kg) for cell phones (based on data from the Environmental Working Group): 38, 55, 86, 145. Here are ten bootstrap samples: {38, 145, 55, 86}, {86, 38, 145, 145}, {145, 86, 55, 55}, {55, 55, 55, 145}, {86, 86, 55, 55}, {38, 38, 86, 86}, {145, 38, 86, 55}, {55, 86, 86, 86}, {145, 86, 55, 86}, {38, 145, 86, 55}.
a. Using only the ten given bootstrap samples, construct an 80% confidence
b. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the population standard deviation.

The percentages for these 10 counties are 20 30 48 18 45 51 12 62 35 25 Assuming that the population standard deviation, sigma, is 12, calculate a 95% confidence interval estimate of the mean percent of residents wearing a mask in Texas. 1. 27% - 42% 2. 23% - 46% 3. 24% - 45% 4. 26% - 43%arrow_forwardIn Exercises 5–8, use the relatively small number of given bootstrap samples to construct the confidence interval. Online Buying In a Consumer Reports Research Center survey, women were asked if they purchase books online, and responses included these: no, yes, no, no. Letting “yes” = 1 and letting “no” = 0, here are ten bootstrap samples for those responses: {0, 0, 0, 0}, {1, 0, 1, 0 }, {1, 0, 1, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}, {0, 1, 0, 0}, {0, 0, 0, 0}, {0, 0, 0, 0}, {0, 1, 0, 0}, {1, 1, 0, 0}. Using only the ten given bootstrap samples, construct a 90% confidence interval estimate of the proportion of women who said that they purchase books online.arrow_forward1) A Gallup poll of 1015 randomly selected adults found that 69% would oppose a law that limited the size of soft drinks and other sugary beverages served in restaurants. Calculate and interpret a 95% confidence interval for the proportion of all adults that would oppose a law limiting the size of soft drinks.arrow_forward
- 1) A consumer magazine polls cell-phone-users to see if they are happy with their phones and would purchase the same model again. They randomly selected cell-phone-users and found the following: 429 of 550 owners of iPhones would purchase their phone again, and 324 of 450 owners of Androids would purchase the same phone again. a) Check the assumptions for comparing proportions . b) Find a 95% confidence interval (Two-Proportion z-Interval) for the difference in the proportions. c) Interpret your interval in the context of the problem. What does the confidence interval say about the difference in the satisfaction of the two types of owners? Hint: pay attention to the signs on the LB & UB .arrow_forwardA) What proportion of commercial airline pilots are more than 40 years of age? Suppose an analyst has access to a list of all pilots who are members of the Air Line Pilots Association. If this list is used as a frame for the study, she can randomly select a sample of pilots, contact them, and ascertain their ages. From 89 of these pilots so selected, she learns that 48 are more than 40 years of age. Construct an 85% confidence interval to estimate the population proportion of commercial airline pilots who are more than 40 years of age. B) Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Regina at rush hour by standing on the corner of Victoria Avenue and Albert Street and counting SUVs. You believe the figure is no higher than 0.40. If you want the error of the confidence interval to be no greater than 0.03, how many cars should you randomly sample? Use a 90% level of confidence.arrow_forwardSuppose that a safety group surveyed 1,200 drivers. Among those surveyed,78% said that careless or aggressive driving was the biggest threat on the road, and 33% said that cell phone usage by other drivers was the driving behavior that annoyed them the most. Based on these data and assuming that the sample was a simple random sample, construct and interpret a 99% confidence interval estimate for the true proportion in the population of all drivers who are annoyed by cell phone users. The confidence interval estimate is _____ to _____. (Round to three decimal places as needed. Use ascending order.)arrow_forward

Seating Choice In a 3M Privacy Filters poll, respondents were asked to identify their favorite seat when they fly, and the results include these responses: window, window, other, other. Letting “window” = 1 and letting “other” = 0, here are ten bootstrap samples for those responses: { 0, 0, 0, 0}, {0, 1, 0, 0}, {0, 1, 0, 1}, {0, 0, 1, 0}, {1, 1, 1, 0}, {0, 1, 1, 0}, {1, 0, 0, 1}, {0, 1, 1, 1}, {1, 0, 1, 0}, {1, 0, 0, 1}.
