suo ose that he sting back to knoe length foragroup of adults has ano mal d tribut n the design of diferent seats, including aircraft seats, train seats, theater seats with a mean of ?=241r and a sta dard de ati -11n These of high if P(x or greater)s0.01 and a value is s seats. Instead of using 0 05 for identifying significant values use the significant values from those that are not significant Using these criteria, is a back-to-knee length of 26 3 in significantly high? Find the back-to-knee lengths separating significant values from those that are not significant Back oknee lengths greater than ? in and less than in are not significant, and values outside that ran e are considered significant (Round to one decimal place as needed) Using these criteria, is a back-to-knee length of 26.3 in significantly high? A back-to-knee length of 26.3 in significantly high because it is the range of values that are not considered signfcant O Type here to search tD 1o 0 9 6 3

Explanation / Answer

Ans:

P(Z<=z)=0.01

z=normsinv(0.01)=-2.33

lower cut off,x=24.1-2.33*1.1=21.5

P(Z>=z)=0.01

z=normsinv(0.99)=2.33

upper cut off=24.1+2.33*1.1=26.7

A length of 26.3 is not significantly high,as it is within the range of values which are not considered significant.
