A supplier to a car manufacturer produces a certain valve and seal used in their cars. The sizes of these
seals and valves are closely monitored to ensure the parts actually work. Here are summary statistics on
the diameters for these valves and seals (in millimeters).
Mean
Standard deviation
Valve
Hy = 50
Oy = 0.3
Seal
His = 51
Os = 0.4
Both distributions are approximately normal. A seal properly fits a valve if the seal's diameter is larger than
the valve's diameter, but the difference can't be more than 2 mm. Suppose we choose a valve and seal at
random and calculate the difference between their diameters. We can assume that their diameters are
independent.
Find the probability that the seal properly fits the valve.
You may round your answer to two decimal places.
P (proper fit)

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?
