Samuel orders four DVDs from an online music store. Each DVD costs $9.99. He has a 20% discount code , and sales tax is $6.75% .
leonid [27]
$34.66
9.99 x 4 = $39.96
minus 20% is 31.96 unless you round up which would be $31.97
6.75% sales tax on 31.96 is $2.1573
6.75% sales tax on 31.97 is $2.1579

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 46
Luba_88 [7]

Answer:

1.) .800

2.).779 to .821

Step-by-step explanation:

We must assume that the sample that we are given to work with is representative of the population, in which case we just need to find the proportion of people in the sample who don't smoke. This is \frac{1738}{2172} = .8002, or .800 rounded to three decimal places.

Part 2 will build off the answer in step 1. The middle of the confidence interval will be the estimate gained from the sample, or .800. The critical value of 98% equals 2.326 when using the normal model. The standard deviation can be calculated using the formula \sqrt{\frac{(proportion)(1-proportion)}{n} }. Plugging in the numbers you get \sqrt{\frac{(.8)(.2)}{2172} }= .009.

This means the confidence interval is .800±.021
