Test 1
One paper sheet of notes front & back Must be unique to you
May use Excel, Minitab and Calculator (no phones). No open spreadsheets. Only Exam may be open.
Topics
One sample: (Chapter 8, 9 & 11)
Confidence Intervals for the mean, proportion and variance (standard deviation)
Mean—sigma known->z, sigma unknown->t
Proportion ->z
Variance->chisquare
Sample distributions for a test of hypotheses.
All tests must include: hypotheses, test-statistic, p-value, statistical decision and practical decision.
Calculate sample size for Confidence Intervals for mean and proportion.
Two sample: (Chapter 10 & 11)
For means—independent groups sigma known->z, sigma unknown->t
Pool if variances are equal.
--not independent (2 measures on same individual)paired t-test
For proportionsz pool if test of hypothesis, do not pool if Confidence interval
For variances->F test
