In this question we simple wish to calculate the standard error and margin of error from the population. This can be done purely using the standard deviation and sample size.
Standard error
= std dev / (SQRT) n
= 11.5 / SQRT of 70
= 11.5 / 8.366
= 1.374
Margin of error is the standard error multiplied by a Z value that correspondence to a confidence percentage. At a 95% confidence the Z value is 1.96. Therefore
MOE = 1.96 x 1.374 = 2.69
And as your area(s) is 5050 square meters, the diameter should be roughly 80.1 meters
Just use the word bank to fill in the blanks. Each letter they give you in the picture is the beginning of the words. So the first one to the left is a C______ and f_____ that would be Cold front. Do the same for the others.
