... Example 110: In a 2011 report by the CDF (Children’s Defense Fund), it was reported that a random sample of 29 black males with only a high school degree earned on average $25,418. The standard deviation is estimated to be $5,500. Use the sample data and a 95% confidence level to find the margin of ...

ANOVA
... Chapter 12 presents the general logic and basic formulas for the hypothesis testing procedure known as analysis of variance (ANOVA). The purpose of ANOVA is much the same as the t tests presented in the preceding chapters: the goal is to determine whether the mean differences that are obtained for s ...

... Approximate the Binomial Distribution To develop a confidence interval for a proportion, we need to meet the following assumptions. 1. The binomial conditions, discussed in Chapter 6, have been met. Briefly, these conditions are: a. The sample data is the result of counts. b. There are only two poss ...

Package `RPtests`
... The function works by first computing residuals from a regression of y on x. Next B sets of errors generated through rand_gen are added to a signal derived from beta_est and aritificial residuals are computed. The option resid_only=TRUE then outputs these residuals along with the original residuals, ...
