approximately 14–16 pounds
approximately 11–19 pounds
approximately 9–21 pounds

First Option

Approximately 13–17 pounds

Step-by-step explanation:

We know that the mean weight of dogs is:

The standard deviation is:

We are looking for a Z score for which it is met that:

According to the empirical rule, for a standard normal distribution it is satisfied that 68% of the data is in a range of one standard deviation above the mean and one standard deviation below the mean. This means that:

Then

Therefore

a is the right answer
