The weight of a basketball is normally distributed with a mean of 17 oz and a standard deviation of 2 oz. suppose 500 different basketballs are in a warehouse. about how many basketballs weigh more than 19 oz?

79 balls.  

Step-by-step explanation:

We have been given that the weight of a basketball is normally distributed with a mean of 17 oz and a standard deviation of 2 oz.

Let us find the z-score for the weight 19 oz.

Let us find P(z>1) using normal distribution table.

So the probability of a basketball having weight more than 19 oz is 0.15866. As there are 500 basketballs in the warehouse, so the total number of basketballs having a weight more than 19 oz will be:

Therefore, 79 balls weigh more than 19 oz.
