You may need to use the appropriate appendix table to answer this question. Automobile repair costs continue to rise with the average cost now at $367 per repair.t Assume that the cost for an automobile repair is normally distributed with a standard deviation of $. the following questions about the cost of automobile repairs. (a) What is the probability that the cost will be more than $490? (Round your answer to four decimal places.) (b) What is the probability that the cost will be less than $220? (Round your answer to four decimal places.) (c) What is the probability that the cost will be between $220 and $490? (Round your answer to four decimal places.) (d) If the cost for your car repair is in the lower 5% of automobile repair charges, what is your maximum possible cost in dollars? (Round your answer to the nearest cent.) 2$ Need Help? Read It

Look at this histogram of heights from the GSS, which happens to be a case where a variable is relatively close to Normally-distributed (Normal curve laid atop for reference). Although it is tough to “eyeball” standard deviations, I am going to give you a list of values that could possibly describe one standard deviation of this distribution. Only one is even in the “ballpark”. Please select it based on your knowledge of Normal distributions. a. One inch b. Four inches c. 20 inches d. 50 inches

Which of the following statements is not true?     There is only one median for each variable.     One definition of the median states that, for an odd number of observations, the median is the middle score when scores are placed in order of magnitude.     Another term for the median is 50th percentile.     The median is generally more sensitive to (i.e., affected by) the presence of a few extreme observations than is the mean.
