Sagot :
Answer: 34% (approximate)
=================================================
Explanation:
We have 7 at the center. Going 2 units to the left of center gets us to 7-2 = 5. Going 2 units to the right of center gets us to 7+2 = 9.
Since the mean is 7 and the standard deviation is 2, this tells us that the values 5 and 9 are exactly one standard deviation away from the mean.
Due to the empirical rule (aka 68-95-99.7 rule), we just found that roughly 68% of the population is between 5 and 9.
Half of this is 68/2 = 34%, so this is the percent of values between 7 and 9.
