Six Problem Types

Exploring Data

• Dot plot, bow plot (min & Q1 & med & max), outlier
• mean, median of distributions (normal, skewed right, skewed left)

Least Square Regression Line (LSRL)

• predicted
• meaning of slope, correlation, coefficient of determination (r^2)
• inference for slope (t-test)

Sampling distribution of x bar

• CLT mean & standard dev.
• transformation (y = a+bx; x = random variable)
• probability

C% Confidence Interval for means & proportions

• construct C% CI
• Interpretation
• Statistical Inference
