The weights of 1000 onions from a certain farm follow a normal distribution with a mean of 150 g and a standard deviation 15 g from the data we can conclude that about blank onions way more than 165 g in about blank onions way less than 135 g

About 159 weigh more than 165 g and about 159 g weigh less Than 135 g

Step-by-step explanation:

Given that :

Mean, μ = 150

Standard deviation, σ = 15

Using the Zscore formula :

Zscore = (x - μ) / σ

For x > 165

P(x > 165)

Z = (165 - 150) / 15

Z = 15 /15 = 1

P(Z > 1) = 0.15866 (Z probability calculator)

1000 * 0.15866 = 158.66 = 159

For x < 135

P(x < 135)

Z = (135 - 150) / 15

Z = - 15 /15 = - 1

P(Z > - 1) = 0.15866 (Z probability calculator)

1000 * 0.15866 = 158.66 = 159
