A toy American Eskimo dog has a mean weight of 8 pounds with a standard deviation of 1 pound. Assuming the weights of toy Eskimo dogs are normally distributed, what range of weights would 95% of the dogs have? a. 7-9 pounds b. 6-10 pounds c. 5-11 pounds d. 4-12 pounds
1 answer:
Answer:
Option b) 6-10 lbs
Step-by-step explanation:
Given that X, the weight of toy American Eskimo dog has mean of 8 pounds with a standard deviation of 1 pound
For 95% of the dogs according to normal distribution would lie between 2 std deviations on either side of the mean.
i.e. lower bound= Mean- 2 std deviation = 8-2 =6
Upper bound = Mean +2 std dev = 8+2 =10
Hence range of weights would be
6-10 lbs

To find the diameter of the radius you need to multiply 3.5 x 2 = 7
(12)(7)(6x)=504x
(12 * 7 * 6)(x)=504x
(7)(12)(6) + x=504+x
12(7 + 6x)=84+72x
12 + 7 + 6x=19+x
wee see that
A*B=(A)(B)
