A certain rail company uses a method called demand pricing for setting the prices of their seats. The price per seat starts at a fixed amount. As the train starts to fill up, the prices gradually
increase. A consumer watchdog agency selected a random coach car on a train traveling
between New York and Philadelphia. They asked each traveler for the price paid for the seat.
The following is the result of their survey.

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
