Many industrial engineering IE majors choose to complete a m

Many industrial engineering (IE) majors choose to complete a minor in safety & health, quality, or construction management (CM). Of 100 IE students, 15 will complete a safety & health minor (S&H;), 10 will complete a quality minor (Q), 20 will complete a CM minor only, and 5 will complete both a safety & health minor and a quality minor. If a professor wishes to advise all of the students completing a minor, how many students will he/she need to advise? 30 35 40 45 A student comes to this professor for advising. If he/she is minoring in quality, what is the probability that he/she is also completing a minor in safety and health? 50% 33% 25% Unknown Given the t-distribution, what is the value of to.io when you have a sample size of 5? 2.015 1.476 2.132 1.533

Solution

9.Given the t distribution, the value of t0.10, with sample size 5 will be:

t(0.10,5-1)=t(0.10,4)=+/-2.132 for a two tailed test

and t(0.10,4)=1.533 for a one tailed test.
