Qmb Final Exam Solved 100% Correct

QMB Final Exam Solved 100% CorrectSteps to find a CI - ANS-1. Determine if Quant or prop2. determine if z or test test3. use the appropriate formula :Quant=>x±z*o/√n or x±t*s/√nProp=>p±z*√(p(1-p)/n4. to find z-score use (1-CI%)/2 +CI% in the norm.inv function5. Do the mathSteps to determine a sample distribution - ANS-1. Determine if quant or prop2. Determine if they want area under curve or z-score3. Determine if SE is given if not SE=o/√n4. determine if the sample>5% of the population if so use the FCF which is √(N-n)/(N-1)5. if area under curve use =norm.dist if they want a z-score use =norm.invSteps for a single mean tests - ANS-1. Determine your null and alternative hypo2.Determine if quant or prop3. If Quant Determine if z or t test 4a. If quant find either the z-test stat->(x-Uo)/(o/√n) or t-test stat ->(x-Uo)/(s/√n)4b. if prop find the z-test stat ->(p-Po)√(Po(1-Po)/n5. Determine if they want a p-value or a rejection region6. P-Value =norm.dist(test stat,0,1,1) *if it is a two tailed test multiple your p-value by two7. Rejection region =norm.dist(test stat,0,1)How to continuous random variable distributions - ANS-1. Determine if its uniform or normally distributed2. If it is uniform use the formula determine the expect
