Answer:
Confidence interval for the mean consumption of milk per week among males over age 25 in 85% confidence level is (2.8≤μ≤3.0)
Step-by-step explanation:
Consumption of milk among males over age 25 can be found using the formula:
M±
where M is the <em>sample mean</em>, z is the corresponding <em>z-score for 85% confidence level</em>, s is the <em>population standard deviation</em>, N is the <em>sample size</em>.
In this sample, mean of milk consumption per week among males over age 25 is 2.9 liters. Corresponding z-score for 85% confidence interval is 1.440. standard deviation of the sample is 1.1. And sample size is 513. When we put these numbers in the formula, we got:
2.9±
=2.9±0.07
$0.70 per candy.
$78 divided by 112 gives $0.696, so by rounding off, you get 0.70
2x(1+3)=7 is the factored form
