A grocery store purchases melons from two distributors, J & K. Distributor J provides melons from organic farms. The distribution of the diameters of the melons from distributor J is approximately normal with mean with 133 millimeters and standard deviation 5 mm. For a melon selected at random from distributor J, what is the probability that the melon will have a diameter greater than 137mm?

Respuesta :

Answer: 0.2119

Step-by-step explanation:

Find the z-score.

(x - μ)/σ

The equation would be:

(137-133)/5 = 0.8

p-value = 0.7881

Subtract that from 1.

1 - 0.7881 = 0.2119
