Question

PLEASE! What I am looking for is the TI 84 step by step calculations only. How to input the data into the calculator in order to gain the correct result. These questions have already been answered. The TI 84 steps are what I am looking for, not excel and not an explanation; if you cannot include TI 84 steps then please do not answer. Thank you so much for your help!!

TEXT: A common design requirement is that an environment must fit the range of people who fall between the 5th percentile for

women and the 95th 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 of the knee. Males have sitting knee heights that are normally

distributed with a mean of 21.4 in. and a standard deviation of 1.3 in. Females have sitting knee heights that are normally

distributed with a mean of 19.1 in. and a standard deviation of 1.2 in. Use this information to answer the following

questions.

A. What is the minimum table clearance required to satisfy the requirement of fitting 95% of men?

B. Determine if the following statement is true or false. If there is clearance for 95% of males, there will certainly be

clearance for all women in the bottom 5%.

C. The author is writing this exercise at a table with a clearance of in. above the floor. What percentage of men fit this

table?

D. What percentage of women fit this table?

E. Does the table appear to be made to fit almost everyone? Choose the correct answer below.

3. A common design requirement is that an environment must fit the range of people who fall between the 5 percentile for women and the g5th 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 of the knee. Males have sitting knee heights that are normally distributed with a mean of 21.4 in. and a standard deviation of 1.3 in. Females have sitting knee heights that are normally distributed with a mean of 19.1 in and a standard deviation of 1.2 in. Use this information to answer the following questions What is the minimum table clearance required to satisfy the requirement of fitting 95% of men? 23.5 in. (Round to one decimal place as needed.) Determine if the following statement is true or false. If there is clearance for 95% of males, there will certainly be clearance for all women in the bottom 5%. O A. The statement is false because some women will have sitting knee heights that are outliers. O B. The statement is true because some women will have sitting knee heights that are outliers. c. The statement is true because the 95th percentile for men is greater than the 5th percentile for women. O D. The statement is false because the 95thpercentile for men is greater than the 5th percentile for women. The author is writing this exercise at a table with a clearance of 23.5 in. above the floor. What percentage of men fit this table? 94.69 b. (Round to two decimal places as needed. What percentage of women fit this table? 99.99 (Round to two decimal places as needed.) Does the table appear to be made to fit almost everyone? Choose the correct answer below. O A. The table will fit only 5% of men. O B. The table will only fit 1 9% of women. C. The table will fit almost everyone except about 5% of men with the largest sitting knee heights. O D. Not enough information to determine if the table appears to be made to fit almost everyone.

Explanation / Answer

Solution:

A. invnorm(0.95, 21.4, 1.3) = 23.5

B. The statement is true because the 95th percentile for men is greater than the 5th percentile for women.

C. normcdf(-10^99,23.5,21.4, 1.3) = 0.9469

D. normcdf(-10^99,23.5,19.1, 1.2) = 0.9469

E. The table will fit almost everyone except about 5% of men with largest sitting knee heights.
