Normal Distributions Not yet answered Points out of A magazine reported that on average, American drivers will be involved in 3.4 car accidents while driving 100 over their lifetime, with a standard deviation of 0.68. Number of accidents for American drivers follows a F Flag normal distribution. Four Americans who are no longer driving were randomly selected. What is the question probability that their average number of accidents while driving will be larger than 4? P(X > 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? What is the rule of thumb for normalizing the sampling distribution of means? np > 10 and nq 2 10 n > 30 np 2 30 and nq 2 30 n > 10 Previous page Next page
