The accompanying table shows the height (in inches) of 8 high school giris and their scores on an IQ test. Complete parts (a) through (d) below. Click here to view the data table. Click here to view the table of critical values for the Pearson comrelation coefficient (a) Display the data in a scatter plot. Choose the correct graph below. OA OB. Oc. 130 130 120 120 110- 100 sot so Height inches) Height ndhes) Height nches He ndhes (b) Calculate the sample correlation coeficientr. (Round to three decimal places as needed.) (c) Describe the type of correlation, if any, and interpret the correlation in the context of the data. There is inear corelation. Interpret the comelation. Choose the correct answer below. OA As high school girts' heights increase, their 1Q scores tend to decrease. OB. As high school girts' heights increase, their 1Q scores tend to increase. OC. Based on the corelation, there does not appear to be a linear relationship between high school giris' heights and their IQ scores. OD. Based on the comelation, there does not appear to be any relationship between high school giris' heights and their 1Q scores. OE Increases in high school giris' heights cause their la scores to decrease. OF. Increases in high school girls' heights cause their IQ scores to increase. (d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the corelation coefficient. Let a0.01. The critical value is O Therefore, there V sufficient evidence at the 1% level of significance to conclude that Vbetween high school girts' heights and their 1Q scores .
