Astudy was done to determine whether there is a relationship between snoring and the risk of heart disease. among 1,105 snorers in the study, 88 had heart disease, while only 22 of 1,379 nonsnorers had heart disease.

(a) determine a 95% confidence interval that estimates p1 − p2 = difference in proportions of snorers and nonsnorers who have heart disease. (let p1 be the proportion of snorers and p2 be the proportion of nonsnorers. round your answers to three decimal places.)

answer: $13,622.84

step-by-step explanation: check the picture for info and stats : )

55 degrees because 55+55=110 degrees

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
