First we need the area of the whole shape (A=l*w)
A:A=7*5 or 35 (7 because you add 3 and 4)
B:A=3*4 or 12
C:A=4*4 or 16
D:A=3*9 or 27 (9 because you add 5 and 4)
So the whole area is 35+12+16+27 = 90
Then we do the part divided by the whole to find probability
=27/90 which can be simplified to 3/10
Hope this helps
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
