A common design requirement is that an environment must t the range of people who fall between the 5t"I percentile for women and the 55"" percentile for men. In designing an assembly work table. the sitting knee height must be considered. which is the distance from the bottom of the feet to the top ofthe knee. Males have sitting knee heights that are normally distributed with a mean of 21.1 in. and a standard deviation of 1.1 in. Females have sitting knee heights that are normally distn'buted with a mean of 15.4 in. and a standard deviation of 1.5 in. Use this information to answer the following questions. What is the minimum table clearance required to satisfy the requirement of fitting 55% of men? D in. (Round to one decimal place as needed.) Determine ifthe following statement is true or false. Ifthere is clearance for 95% of males. there will certainly be clearance for all women in the bottom 5%. [:1 A. The statement is true because some women will have sitting knee heights that are outliers. [:1 E. The statement is true because the 55th percentile for men is greater than the 5th percentile for women. [:1 C. The statement is false because the 55th percentile for men is greater than the 5th percentile for women. [:1 D. The statement is false because some women will have sitting knee heights that are outliers. The author is writing this exercise at a table with a clearance of 23.? in. above the oor. What percentage of men t this table? |:|% [Round to two decimal places as needed.) What percentage of women t this table? |:|% [Round to two decimal places as needed.) Does the table appear to be made to t almost everyone? Choose the correct answer below. [:1 lift. The table will t almost everyone except about 1% of men with the largest sitting knee heights. [:1 E. The table will only t 1% ofwomen. [:1 C. The table will t only 1% ofmen. [:1 D. Not enough information to determine if the table appears to be made to t almost everyone
