The weight of oranges growing in an orchard is normally distributed with a mean weight of 7 oz. and a standard deviation of 1.5

Katena32 [7]

Answer:

2 to 11 ounces would be the interval.

Step-by-step explanation:

Add 3 standard deviations above and below the mean to get the range in which 99.7% of the data in a normal distribution will fall

6.5 + 4.5 = 11

6.5 - 4.5 = 2.
