... If television networks claim that the average length of time devoted to commercials in a 60-minute program is 12 minutes, we would use H0: = 12 minutes as our null hypothesis in a study regarding the average length of time devoted to commercials. Finally, if a repair shop claims that it should take ...

... total claim amount is normally distributed with mean 10,000 and standard deviation 2,000; the same is true for company B only the mean is 9,000 and the standard deviation is 2,000. Assume that claims for the two companies are independent. What is the probability that in the coming year the amount of ...

... The median is the value of a variable that divides the observations on that variable in half. If we ordered our observations on a variable from lowest to highest, the median observation is the one in the middle. With an even number of observations there is no true median. The median is most commonly ...
