Suppose that one of these drivers is selected at random. Define the followwing events:
= the event that a driver was in a city with a speed limit above 25 mph.
S= the event that a driver is speeding.
a) The table below shows the possible combinations of F and S. For each combination,
calculate the probability that the combination would be observed for a randomly
selected driver. Enter these probabilities into the corresponding cell in the table.

Quality control at the plant is concerned the machine is not working correctly and that it is producing a different distribution of colors. They take a random sample of 940 plain M&M's. A Chi-Square Goodness of Fit Test is performed. Calculate the value of the chi-square goodness of fit test statistic given the observed counts below. Enter your answer to 3 decimal places.
