The correct answer is Approximately 6-10 pounds

Step-by-step explanation:

According to the given statement a toy American Eskimo dog has a mean weight of 8 pounds with a standard deviation of 1 pound

According to normal distribution 95% dogs lie between 2 std deviation on either side of the mean.

Therefore lower bound = 8-2 = 6

Upper bound = 8+2 = 10

Thus the range would be approximately 6-10 pounds ...
