The time that it takes for the next train to come follows a Uniform distribution with f(x) =1/25 where x goes between 6 and 31 minutes. Round answers to 4 decimal places when possible. This is a Correct distribution. It is a Correct distribution. The mean of this distribution is 18.50 Correct The standard deviation is Incorrect Find the probability that the time will be at most 28 minutes. Incorrect Find the probability that the time will be between 12...

The mean time it takes for workers at a factory to insert a delicate bolt into an engine is 15 minutes. The standard deviation of time to insert the bolt is 4.0 minutes and the distribution of time is approximately normally distributed. 97.5% of the time, the bolt is inserted in less than which time value? Round to the nearest whole number.
The time it takes for a Madonna concert to sell out follows a normal distribution with an average sell out time of 80 minutes with a standard deviation of 15 minutes. Fill in the values for the normal curve for the time to sell out. From left to right, the values would be: b.) Quantity, what percent of shows would they expect to sell out in 50 minutes or less? c) How many shows out of the 50 would be expected to take...
