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.

The sampling distribution of the sample means for the random sample of 100 dogs will be 0.25.
<h3>How to compute the sample mean?</h3>
From the given information, the population distribution of the QDA scores for the fur of dogs is roughly uniform with mean 5.4 and standard deviation is 2.5.
In this case, the sampling distribution of the sample means will be:
= ✓SD/n
= ✓(2.5)²/100
= ✓0.0625
= 0.25
In conclusion, the correct option is 0.25.
