Answer:
The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.
Which weights are within 2 standard deviations of the mean? Check all that apply.
8.4 lbs
8.9 lbs
9.5 lbs
9.8 lbs
10.4 lbs
10.9 lb
Step-by-step explanation:
The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:
9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)
8.5 ≤ x ≤ 10.5
