Step-by-step explanation:
Given that,
The length of a rectangle is (0.8x - 1.6) units
Width of a rectangle is (1/4x +1 ) units.
It is assumed to find the area of a rectangle.
AREA = l b, l is length and b is width
So,
Hence, this is the required solution.
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
