Answer:
Step-by-step explanation:
The probability distribution of sampling distribution is known as it sampling distribution.
The mean and standard deviation of the proportion is given by :-
, where p =population proportion and n= sample size.
Given : According to a survey, 50% of Americans were in 2005 satisfied with their job.
i.e. p = 50%=0.50
Now, for sample size n= 1000 , the mean and standard deviation of the proportion will be :-
Hence, the mean and standard deviation of the proportion for a sample of 1000:
Answer:
71°
Step-by-step explanation:
Kaia's window is in the shape of a trapezoid. Three of the angles are 80°, 100°, and 109°. What is the measure of the fourth angle?
The sum of angles in a trapezoid is equal to = 360°
We are given 3 angles in the trapezoid as: 80°, 100°, and 109°.
The measure of the fourth angle is calculated as:
360° = 80°+ 100° +109° + fourth angle
360° - (80°+ 100° +109°)
360° - 289°
= 71°
The measure of the fourth angle is 71°
The answer would be 8 2/3
