Answer:
Step-by-step explanation:
The correct answer would actually be 15 because (-5) multiplied by -3 makes it positive 15.
What I would do for this problem, is move all the terms that don't contain m to the right side, and then solve.
m = 4/5.
Answer:
n=3.8416≅4
So Minimum Sample Size is 4
Step-by-step explanation:
In order to find the minimum sample size, the formula we use will be:

Where:
n is sample size
Z is the distribution
S is the standard deviation
E is the Margin of error
S=3 ,E=3
For Z:
Alpha=1-0.95=0.05
Alpha/2=0.025=2.5%
From Cumulative Standard Distribution Table:
Z at Alpha/2 = 1.960

n=3.8416≅4
So Minimum Sample Size is 4
