Below are four bivariate data sets and their scatter plots. (Note that all of the scatter plots are displayed with the same scale.) Each data set is made up of sample values drawn from a population.- **Figure 1:** - Data set (x, y) - (10, 5.0) - (8.0, 4.1) - (13.0, 7.4) - (9.0, 4.7) - (11.0, 5.3) - (14.0, 9.0) - (6.0, 4.1) - (4.0, 3.0) - (12.0, 6.5) - (7.0, 4.4) - (5.0, 3.8) - Scatter plot: Displays a clear negative linear trend.- **Figure 2:** - Data set (u, v) - (10.0, 27.0) - (2.0, 42.0) - (3.0, 33.0) - (4.0, 52.0) - (5.0, 41.0) - (6.0, 69.0) - (7.0, 60.0) - (8.0, 74.0) - (9.0, 72.0) - (10.0, 80.0) - Scatter plot: Displays a moderate positive linear trend.- **Figure 3:** - Data set (w, p) - (1.0, 7.8) - (2.0, 9.0) - (3.0, 7.4) - (4.0, 5.2) - (5.0, 8.2) - (6.0, 6.0) - (7.0, 4.5) - (8.0, 8.5) - (9.0, 8.6) - (10.0, 5.4) - Scatter plot: Displays a potential nonlinear pattern.- **Figure 4:

Consider a sample with data values of 29, 27, 22, 17, 32, 38, 30, and 27. Compute the 20th, 25th, 65th, and 75th percentiles. Step 1 Recall that a percentile gives insight to how data are spread between the smallest and largest values. The pth percentile of a set of data indicates that p% of the data are below that value, and (100 − p)% are above that value. There are two components of the pth percentile: the location within the data and the actual value. The formula for finding the location of the percentile, denoted Lp, follows where p is the percentile and n is the number of observations in the ordered data set. Lp = p 100 (n + 1) The first step in calculating a percentile is to order the data in ascending order. The ordered data are below. 17 22 27 27 29 30 32 38 There are n = 8 observations in the data. Find the location of the p = 20th percentile. Lp = p 100 (n + 1) L20 = 20 100 + 1 =
