(b) Examine the $95 \%$ confidence intervals for the four samples shown in the printout. Their previous director of quality was displaying the data with a one sided confidence interval. Confidence interval for a proportion from one sample (p) with a dichotomous outcome. They are currently limited to Minitab 14.
If n < 30, use the t-table with degrees of freedom (df)n-1. Example: In the battery experiment, the individual 95 confidence intervals for the four mean shown in the Minitab output have a. If n > 30, use and use the z-table for standard normal distribution. How do the boxplots for the four samples differ? Why should you expect the boxplots to differ? Confidence interval for the difference in a continuous outcome (d) with two matched or paired samples. The boxplots and confidence intervals for four different samples are shown in the accompanying figures. In Minitab, we can simulate the drawing of random samples of size 20 from this population $(\text ,$ with boxplot selected in the graphs).
Critical Thinking: Boxplots and Confidence Intervals The distribution of heights of 18 -year-old men in the United States is approximately normal, with mean 68 inches and standard deviation 3 inches (U.S.
