1.9
9.5% = 0.095
0.095* 20 = 1.9
Convert 15% into a decimal. (0.15) Then multiply that by 550.
Answer:
The standard error of the mean is 0.02
Step-by-step explanation:
Here, we want to calculate the standard error of the mean.
Mathematically;
standard error of mean = SD/ √n
where SD is the standard deviation and n is the number of samples
From the question, SD = 0.22 and n = 121
Inserting this into the equation
Standard error of the mean = 0.22/√121
= 0.22/11 = 0.02
Answer:
0.57
Step-by-step explanation:
If you calculated it you would get 20.25 so it is irrational
