What the data means about the amount of money people spend on purchasing accessories for the their mobile phones is that;
on the average, people spend between 43 and 57 dollars on every accessory they buy.
<h3>Confidence Interval</h3>
We are told that;
Mean is $50
Standard deviation from the mean is $7
From the empirical rule, since standard deviation from the mean is $7, then we can conclude that the confidence interval is;
CI = 50 ± 7
CI = (50 - 7), (50 + 7)
CI = (43, 57)
In conclusion, this means that on the average, people spend between 43 and 57 dollars on every accessory they buy.
