Answer:

74% change

Step-by-step explanation:

Percentage is the fraction between two values usually the obtained value against the total obtainable value and multiply by 100.

% change = (value in September / value in july) * 100

% change = (5.51 / 7.45) * 100

% change = 0.7395 * 100

% change = 74%

The margin of error given the proportion can be found using the formula

z* \sqrt{ \frac{p(1-p)}{n} }

Where
z* is the z-score of the confidence level
p is the sample proportion
n is the sample size

We have
z*=2.58
p=0.38
n=80

Plugging these values into the formula, we have:
2.58 \sqrt{ \frac{0.38(1-0.38)}{80} } =0.14

The result 0.14 as percentage is 14%

Margin error is 38% ⁺/₋ 14%
