Suppose that the sittingback-to-knee length for a group of adults has a normal distribution with a mean of mu equals

=24.9 in. and a standard deviation of sigma equals =1.2 in. These data are often used in the design of differentseats, including aircraftseats, trainseats, theaterseats, and classroom seats. Instead of using 0.05 for identifying significantvalues, use the criteria that a value x is significantly high ifP(x or greater) 0.01 and a value is significantly low ifP(x or less) 0.01. Find theback-to-knee lengths separating significant values from those that are not significant. Using thesecriteria, is aback-to-knee length of

27.0 in. significantlyhigh?
