Suppose that the sitting back to-knee length for a group of adults has a normal distribution with a mean of u=23.3 in. and a standard devation of e11 in. These are often used in the design of different seats, including aircraft seats, train seats, theater seats, and classroom seats. Instead of using 005 for identitying significa values, use the criteria that a value x is significantly high it P(x or greater) s0.01 and a value is signifcantly low if Px or less) s0.01. Find the back-to-knee length separating significant values from those that are not significant. Using these criteria, is a back-to knee length of 25.6 in. significantly high? Find the back-to-knee lengths separating significant values trom those that are not significant Back-to-knee lengths greater than (Round to one decimal place as needed.) in. and less than in, are not significant, and values ouside that range are considered significant

Question
Suppose that the sitting back-to-knee length tor a group of adults has a normal distribution with a mean of u 23.3 in. and a standard deviation of e=11 in. These 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 significa values, use the criteria that a value x is significantly high it P(x or greater) s0.01 and a value is signifcantly low if P(x or less) s0.01. 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 25.6 in. significantly high? Find the back-to-knee lengths separating significant values from those that are not significant Back-to-knee lengths greater than in. and less than (Round to one decimal place as needed.) in, are not significant, and values outside that range are considered significant
