Answer: 0.02
Step-by-step explanation:
Given: Sample size :
The population proportion
Then,
The formula to calculate the standard error is given by :-
Hence, the standard deviation of the sample proportions (i.e., the standard error of the proportion) is <u>0.02</u>.
For example. 2/4 X 2 would be equal to 4/8
That’s a SSS triangle so you need to use the law of cosines to calculate one of the angles. then use it again to calculate the other than subtract from 180 to find the 3rd
