Answer:
The percentage is 68.26%
Step-by-step explanation:
Before we use the empirical rule , we need to find the value of the z-score
Mathematically;
z-score = (x - mean)/SD
Thus;
z-score = (7.85 - 7.45)/0.4 = 0.4/0.4 = 1
So the percentage we want to calculate now is the percentage of values within 1 standard deviation of the mean
According to the empirical rule, 68.26% of values are within 1 standard deviation of the mean
