Problem 10.49

How large a sample is required in Exercise 10.24 if the power of the test is to be 0.95 when the true average height diers from 162.5 by 3.1 centimeters? Use =0 .02.

Step-by-Step Solution:

Step 1 of 3

C5/C6/C7 numerical summaries  Organize/summarize data o Graphical o Numerical (primarily for quantitative variables)  Location  Measure of location: give “middle” or “typical” values or “central tendency” o Mean: the “center of gravity” of the data (histogram)/ average of a set of numbers  Mean= sum of observations/ sample size  The mean is not resistant to extreme values o Median: midpoint of distribution  At least half of the observations are at or less
