A magazine reported that on average, American drivers will be involved in 3.4 car accidents while driving over their lifetime, with a
standard deviation of 0.68. Number of accidents for American drivers follows a normal distribution. Four Americans who are no
longer driving were randomly selected. What is the probability that their average number of accidents while driving will be larger
than 4?
P(E > 125)
For this problem, we were told that the distribution is normal. If the shape of the distribution was not stated, we would not have
been able to use the normal distribution table to find the probability. What does the Central Limit Theorem tell us to do to be able
to normalize the distribution?
Wha
Increase the standard deviation
the sampling distribution of means?
increase the mean
Increase the sample size
It cannot be normalized
