Suppose that the sitting? back-to-knee length for a group of adults has a normal distribution with a mean of mu equals μ=24.9 in. and a standard deviation of sigma equals σ=1.2 in. These data are often used in the design of different? seats, including aircraft? seats, train? seats, theater? seats, and classroom seats. Instead of using 0.05 for identifying significant? values, use the criteria that a value x is significantly high if? P(x or ?greater) ≤0.01 and a value is significantly low if? P(x or ?less) ≤0.01. Find the? back-to-knee lengths separating significant values from those that are not significant. Using these? criteria, is a? back-to-knee length of 27.0 in. significantly? high?
