Question

5. The manager of a cultured pearl farm has received a special order for two pearls between 7 millimeters and 9 millimeters in diameter. From past experience, the manager knows that the pearls found in his oyster bed have diameters that are normally distributed with a mean of 8 millimeters and a standard deviation of 2 millimeters. Assume that every oyster contains one pearl.

Step 1

To find the z-score for a value x in a normal distribution with mean μ and standard deviation σ, you can use the formula: z = (x - μ) / σ For the lower limit of 7 millimeters: z_lower = (7 - 8) / 2 = -0.5 For the upper limit of 9 millimeters: z_upper = (9 - 8) / Show more…
