Hello,
Suppose that the sittingback-to-knee length for a group of adults has a normal distribution with a mean of
=22.1 in. and a standard deviation of=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 orgreater)0.01
and a value is significantly low ifP(x orless)0.01. Find theback-to-knee lengths separating significant values from those that are not significant. Using thesecriteria, is aback-to-knee length of24.4 in. significantlyhigh?
Find theback-to-knee lengths separating significant values from those that are not significant.
Back-to-knee lengths greater than ____________in. and less than ___________in. are notsignificant, and values outside that range are considered significant.
Thanks in advance!!
