Select the correct answer Gavin collects a certain type of seashell. He has 160 seashells. The seashells' weights are distributed normally, with a mean of 120 grams and a

standard deviation of 26 grams.

How many of the seashells weigh at least 68 grams?

A 134

В.152

C.156

D. 109

C.156

Step-by-step explanation:

Given: Total seashells = 160

mean = 120

population standard deviation = 26 grams

The probability that the seashells weigh at least 68 grams :-'

Total seashells weigh at least 68 grams = 0.9772 x 160 = 156.352≈ 156

Hence, the correct option is C.156
