Answer 1

The area to the left of X=250 in the normal distribution can be interpreted as the probability that a data point is less than 250 and as the percentage of data points that fall below 250.

Step-by-step explanation:

The question asks for two interpretations of the area to the left of X=250, which is given as 0.1497. To interpret this area, we can think of it as a probability.

Interpretation 1: The area to the left of X=250 represents the probability that a randomly chosen data point from the normal distribution is less than 250. In this case, the probability is 0.1497 or 14.97%. This means that there is a 14.97% chance that a randomly chosen data point is less than 250.

Interpretation 2: The area to the left of X=250 represents the percentage of data points that fall below 250 in the normal distribution. In this case, the area is 0.1497 or 14.97%. This means that approximately 14.97% of the data points in the normal distribution are less than 250.
