The empirical rule says that approximately 68% of a normal distribution falls within one standard deviation of the mean. In this case, this would include all values of the variable in the interval
.
The total amount shared by the friends illustrates mean and average, and the amount spent by each friend is $11.5
<h3>How to determine the amount?</h3>
The given parameters are:
- Total = $76
- Tip = $16
- Number of friends = 8
The amount spent by each friend is calculated using:
Amount = (Total + Tip)/Number of friends
So, we have:
Amount = (76 + 16)/8
Evaluate
Amount = 11.5
Hence, the amount spent by each friend is $11.5
