Click here to view the table of critical values for the Pearson correlation coefficie (b) Calculate the sample correlation coefficient r. (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 linear correlation. Interpret the correlation. Choose the correct answer below. O A. As age increases, the number of words in children's vocabulary tends to increase. B. As age increases, the number of words in children's vocabulary tends to decrease. OC. Aging causes the number of words in children's vocabulary to increase. OD. Aging causes the number of words in children's vocabulary to decrease. O E. Based on the correlation, there does not appear to be any relationship between children's ages and the number of words in their vocabulary. O E Based on the correlation, there does not appear to be a linear relationship between children's ages and the number of words in their vocabulary (d) Use the table of critical values for the Pearson correlation.coefficient to make a conolusion about the correlation coefficient. Let a = 0.01. The critical value is Therefore, there V sufficient evidence at the 1% level of significance to conclude
