Transcribed Image Text:Use the accompanying data table to (a) draw a normal probability plot, (b) determine the linear correlation between the observed values and the expected z-scores, (c) determine the critical value in
the table of critical values of the correlation coefficient to assess the normality of the data.

Q
O A. Because the correlation between the expected z-scores and observed values is less than the critical value, it is not reasonable to conclude the data come from a population that is
annroximately normal.
Data Table
B. Because the correlation between the expected z-scores and observed values is greater than the critical value, it is not reasonable to conclude the data come from a population that is
approximately normal.
OC. Because the correlation between the expected z-scores and observed values is greater than the critical value, it is reasonable to conclude the data come from a population that is
approximately normal.
O D. Because the correlation between the expected z-scores and observed values is less than the critical value, it is reasonable to conclude the data come from a population that is approximately
normal.
