In Exercises 21–24, use these parameters (based on Data Set 1 “Body Data” in Appendix B):
• Men’s heights are
• Women’s heights are normally distributed with mean 63.7 in. and standard deviation 2.9 in.
24. Executive Jet Doorway The Gulfstream 100 is an executive jet that seats six, and it has a doorway height of 51.6 in.
a. What percentage of adult men can fit through the door without bending?
b. Does the door design with a height of 51.6 in. appear to be adequate? Why didn’t the engineers design a larger door?
c. What doorway height would allow 40% of men to fit without bending?

The researcher conducts a study among 93 newly diagnosed arthritis patients and finds the mean trough to be 4.1 micrograms/mL with a standard deviation of 2.4 micrograms/mL. The researcher wants to test at the 5% level of significance if the trough is different than previously reported or not. Z statistics will be used. Complete Step 5 of hypothesis testing: Conclusion. State whether or not you would reject the null hypothesis and why. Also interpret what this means (i.e. is the mean trough different from 3.7 or noarrow_forward30% of all college students major in STEM (Science, Technology, Engineering, and Math).
