According to the US. Department of Transportation (DOT), in the U.S. there are an average of 1.88 vehicles per household, with a standard deviation of 0.36 vehicles per household. Suppose that a random sample of 40 households was taken and the sample mean for the number of vehicles per household was computed, and you are interested in a probability about the sample mean. Question 28 1 pts Pick the equation most appropriate to deal with the problem above. Question 29 1 pts If the sample mean is 1.90, then select the most appropriate item that pertains to the problem. 0 2:035 o z=0.06 o z=0.23 O 2 =0.54 Question 30 1 pts What is the probability that the sample mean is less than 1.86 vehicles? 0 0.3943 0 0.4176 0 0.3632 0 0.3213
