The mean is != 15.2 and the standard deviation is σ = 0.9. Find the probability that X is between 14.3 and 16.1.

95%

Step-by-step explanation:

Assuming the distribution is normally distributed with a mean of

and standard deviation

We want to find the probability that X is between 14.3 and 16.1

We find z-scores to get:

We simplify to get:

According to the empirical rule, approximately 95% of the distribution falls within one standard deviation of the mean.
