The table below shows the summary statistics of two variables for correlation analysis. Descriptive Statistics Weight at birth (Kilograms) Age of woman Mean 3.58592 27.04 Std. Deviation 1.830438 6.467 510 510 Note that the sample sizes are both given as 510 even though this is not necessarily the case. Which one of the following is the likely and logical explanation for using 510? O a. There are exactly 510 cases where data is available for both woman age and baby's birthweight O b. SPSS used the sample size calculator to determine the value 510 OC. SPSS extracted 510 cases which did not violate any assumptions for correlation analysis. O d. 510 is a large enough sample and there is no need using more data
