Example 16.13) A person while calculating correlation coefficient between two variables X and Y ob- tained the following results: 11 = 30 ΣΧ-120 ΣΧ600 ΣΥ- 90 ΣΥ2250 and ΣΧΥ356 It was, however, later discovered at the time of checking the calculations that two pairs of observa- tions (8, 10) and (12, 7) were wrongly entered instead of (8, 12) and (10, 8). Determine the correct value of correlation coefficient.
