A simple random sample of 1000 people age 18 or over is taken in a large town. It turns out that 223 people in the sample are newspaper readers. Calculate a 90%-confidence interval for the percentage of people (age 18 and over) in that town who read newspapers. Choose the closest answer. a. (19.7%, 24.9%) b. (21.5%, 23.0%) c. (21.0%, 23.5%) d. (20.1%, 24.5%)

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
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)
A survey asked, "How many tattoos do you currently have on your body?" Of the 1233 males surveyed, 183 responded that they had at least one tattoo. Of the 1042 females surveyed, 139 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. C Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p₁ -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)
Ten engineering schools in the US were surveyed. the sample contains 250 electrical engineers, 80 being women; 175 chemical engineers, 40 being women.

Construct the indicated confidence interval for the difference in proportions. Assume that the samples are Independent and that they have been randomly selected. A survey of randomly chosen adults found that 45% of the 231 women and 61% of the 275 men follow regular exercise programs. Construct a 95% confidence interval for the difference in the proportions of women and men who have regular exercise programs. O A. (-0.165, -0.155) OB. (0.052, 0.268 ) OC. (-0.246, -0.074) O D.

Twenty-two car salespeople were sampled to see how many cars they sold in a month; the following data was obtained: 26, 20, 22, 18, 21, 14, 24, 28, 17, 23, 28, 29, 18, 17, 24, 26, 19, 27, 26, 22, 23, 25 Construct a 95% confidence interval for the mean number of cars sold per month by the population of car salespeople. S = t = Margine of Error: E = We are 95% confident that, on average, car salespeople sell between cars and cars per month.
