TABLES AND FORMULAS FOR MOORE Basic Practice of Statistics Exploring Data: Distributions • Look for overall pattern (shape, center, spread) and deviations (outliers). • Mean (use a calculator): x = x1 + x2 + · · · + xn n = 1 n ! xi • Standard deviation (use a calculator): s = " 1 n! 1 ! (xi ! x)2 • Median: Arrange all observations from smallest to largest. The median M is located (n + 1)/2 observations from the beginning of this list. • Quartiles: The first quartile Q1 is the median of the observations whose position in the ordered list is to the left of the location of the overall median. The third quartile Q3 is the median of the observations to the right of the location of the overall median. • Five-number summary: Minimum, Q1, M, Q3, Maximum • Standardized value of x: z = x! µ ! Exploring Data: Relationships • Look for overall pattern (form, direction, strength) and deviations (outliers, influential observations). • Correlation (use a calculator): r = 1 n! 1 ! # xi ! x sx $ % yi ! y sy & • Least-squares regression line (use a calculator): ŷ = a + bx with slope b = rsy/sx and intercept a = y ! bx • Residuals: residual = observed y ! predicted y = y ! ŷ Producing Data • Simple random sample: Choose an SRS by giving every individual in the population a numerical label and using Table B of random digits to choose the sample. • Randomized comparative experiments: Random Allocation !" #$ Group 1 Group 2 % % Treatment 1 Treatment 2 #$ !" Observe Response Probability and Sampling Distributions • Probability rules: • Any probability satisfies 0 " P (A) " 1. • The sample space S has probability P (S) = 1. • If events A and B are disjoint, P (A or B) = P (A) + P (B). • For any event A, P (A does not occur) = 1! P (A) • Sampling distribution of a sample mean: • x has mean µ and standard deviation !/ # n. • x has a Normal distribution if the popula- tion distribution is Normal. • Central limit theorem: x is approximately Normal when n is large. Basics of Inference • z confidence interval for a population mean (! known, SRS from Normal population): x ± z! !# n z! from N(0, 1) • Sample size for desired margin of error m: n = # z!! m $2 • z test statistic for H0 : µ = µ0 (! known, SRS from Normal population): z = x! µ0 !/ # n P -values from N(0, 1) Inference About Means • t confidence interval for a population mean (SRS from Normal population): x ± t! s# n t! from t(n! 1) • t test statistic for H0 : µ = µ0 (SRS from Normal population): t = x! µ0 s/ # n P -values from t(n! 1) • Matched pairs: To compare the responses to the two treatments, apply the one-sample t proce- dures to the observed di!erences. • Two-sample t confidence interval for µ1!µ2 (in- dependent SRSs from Normal populations): (x1 ! x2) ± t! " s2 1 n1 + s2 2 n2 with conservative t! from t with df the smaller of n1 ! 1 and n2 ! 1 (or use software). • Two-sample t test statistic for H0 : µ1 = µ2 (independent SRSs from Normal populations): t = x1 ! x2 " s2 1 n1 + s2 2 n2 with conservative P -values from t with df the smaller of n1 ! 1 and n2 ! 1 (or use software). Inference About Proportions • Sampling distribution of a sample proportion: when the population and the sample size are both large and p is not close to 0 or 1, p̂ is ap- proximately Normal with mean p and standard deviation ' p(1! p)/n. • Large-sample z confidence interval for p: p̂ ± z! " p̂(1! p̂) n z! from N(0, 1) Plus four to greatly improve accuracy: use the same formula after adding 2 successes and two failures to the data. • z test statistic for H0 : p = p0 (large SRS): z = p̂! p0 " p0(1! p0) n P -values from N(0, 1) • Sample size for desired margin of error m: n = # z! m $2 p!(1! p!) where p! is a guessed value for p or p! = 0.5. • Large-sample z confidence interval for p1 ! p2: (p̂1 ! p̂2) ± z!SE z! from N(0, 1) where the standard error of p̂1 ! p̂2 is SE = " p̂1(1! p̂1) n1 + p̂2(1! p̂2) n2 Plus four to greatly improve accuracy: use the same formulas after adding one success and one failure to each sample.
