A box model is used to calculate a confidence interval in the following scenario:A institution selects 300 households in a town asking about their annual income.They want to construct a confidence interval for the percentage of people havingincome more than $100,000 annually.For each of the following quantities in the box model, select the answer if thequantity is random, not fixed. Leave the quantities that are fixed unselected.O the EV and SE of the sample percentage of households having income more than $100.000 annuallyO the population percentage of households having income more than $100,000 annuallyO the sample percentage of households having income more than $100,000 annuallyO the proportion of 1's in the box model

A survey asked, "How many tattoos do you currently have on your body?" Of the 1241 males surveyed, 182 responded that they had at least one tattoo. Of the 1047 females surveyed, 139 responded that they had at least one tattoo. Construct a 99% 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. P1 Let p, represent the proportion of males with tattoos and p, represent the proportion of females with tattoos. Find the 99% confidence interval for p, - p2. The lower bound is The upper bound is (Round to three decimal places as needed.)

Kit and Casey are each attempting to estimate the proportion of college students who can play at least one musical instrument. They each survey a different random sample of college students, and in each sample, the proportion who can play at least one musical instrument is 0.35. Kit and Casey each use their sample data to construct a confidence interval. Kit's interval is from 0.308 to 0.372 and Casey's interval is from 0.318 to 0.382. One of these intervals was computed correctly, but the other was not. Which interval must be incorrect? O Kit's interval must be incorrect. O It's impossible to answer this question without knowing the sample sizes. O It's impossible to answer this question without knowing the sample sizes or the level of confidence used for each interval. O Casey's interval must be incorrect. O It's impossible to answer this question without knowing the level of confidence used for each interval.
