The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 40 who smoke.

a. Suppose a sample of 1089 Americans over 40 is drawn. Of these people, 806 don't smoke. Using the data, estimate the proportion of Americans over 40 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.
b. Suppose a sample of 861 Americans over 47 is drawn. Of these people, 577 don't smoke. Using the data, construct the 80% confidence interval for the population proportion of Americans over 47 who smoke. Round your answers to three decimal places.

Answers

Answer:

0.259 or 25% or 1/4

and i couldnt figure out b sorry

Step-by-step explanation:

a) The proportion of Americans over 40 who smoke will be 7.075.

b) The population proportion of Americans over 47 who smoke will be 227.2.

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

a) A sample of 1089 Americans over 40 is drawn.

And, Of these people, 806 don't smoke.

b) A sample of 861 Americans over 47 is drawn.

And, Of these people, 577 don't smoke.

Here,

a) A sample of 1089 Americans over 40 is drawn.

And, Of these people, 806 don't smoke.

So, The proportion of Americans over 40 who smoke = 1089 - 806 / 40

                                                                                   = 283 / 40

                                                                                   = 7.075

b) A sample of 861 Americans over 47 is drawn.

And, Of these people, 577 don't smoke.

So, the 80% confidence interval for the population proportion of Americans over 47 who smoke = 80% of (861 - 577)

                                                 = 80% × 284

                                                 = 80/100 × 284

                                                 = 227.2

If MB = 6x-9, and AM = 27, find x.

x=11

Step-by-step explanation:

M is the midpoint this means that we can set AM and BM equal to eachother, once this is done we can solve for x

9x-6=6x+27 (set equal to eachother)

9x=6x+33 (add 6)

3x=33 (subtract 6x)

x=11 (divide by 3)
