Answer:

b. 2.28%.

Step-by-step explanation:

Mean temperatue (μ) = 1000°F

Standard Deviation (σ) = 50 °F

For any temperature value, X, the z-score is given by:

$z=\frac{X-\mu}{\sigma}$

For X= 900°F

$z=\frac{900-1000}{50}\\z=-2.0$

A z-score of -2.0 corresponds to the 2.28-th percentile of a normal distribution. Therefore, the probability that X<900 is:

$P(X$
