This is where Excel comes in handy. There are five main functions in Excel related to the t-distribution (not including the t-test functions in the Data Analysis Toolpak T.DIST T.DIST.RT T.DIST.2T T.INV T.INV.2T In which of the above functions do you INPUT a t-value and get an OUTPUT of a cumulative probability (area under the curve)? Degrees of freedom is a required input for all five functions, so you can ignore that for this question. A) T.DIST and T.INV B) T.DIST, T.DIST.RT, and T.DIST.2T C) T.DIST.2T and T.INV.2T D) T.INV and T.INV.2T

Los Angeles workers have an average commute of 31 minutes. Suppose the LA commute time is normally distributed with a standard deviation of 13 minutes. Let X represent the commute time for a randomly selected LA worker. Round all answers to 4 decimal places where possible.a. Find the probability that a randomly selected LA worker has a commute that is longer than 27 minutes. b. Find the 70th percentile for the commute time of LA workers.  minutes
