In two sets of variables X and Y with 50 observations each, the following data were observedX = 10, S.D. ofx3D37=6, S.D. of Y = 2the Coeficient of correlation between X and Y is 03. However, on subsequent verification it was found pair (X = 10, Y = 6) was inaccurate and hence weeded out. With the remaining 49 pairsof values, how is the original value of correlation coefficient affected ?

While calculating the coefficient of correlation between two variables x and y from 25 pairs of observation, obtained the following results:n= 25, ∑x= 125, ∑x2 = 650, ∑y= 100, ∑y2= 460, ∑xy= 508At the time of checking, it was observed that two pairs of observations were incorrect. Following tables give detailed information about incorrect observation used and correct observation which should have been used. Find the correct value of ‘r’.

The professor of an introductory statistics course has found something interesting: there is a small correlation between scores on his first midterm and the number of years the test-takers have spent at the university. For the 55 students taking the course, the professor found that the two variables number of years Espa spent by the student at the university and score on the first midterm have a sample correlation coefficient r of about -0.36. Test for a significant linear relationship between the two variables by doing a hypothesis test regarding the population correlation coefficient p. (Assume that the two variables have a bivariate normal distribution.) Use the 0.05 level of significance, and perform a two-tailed test. Then complete the parts below. (If necessary, consult a list of formulas.) (a) State the null hypothesis H and the alternative hypothesis H . Aa 0, B H, :0 H : O=0 (b) Determine the type of test statistic to use. (Choose one) ▼ O

A study conducted by students in an AP Psychology classat South Kent School in CT discovered a correlation of-0.38 between students’ hours of sleep (x) and GPAs (y).The scatterplot below displays the relationship. Whatconclusion can be reasonably drawn from these data? A) Students who get more sleep tend to earnhigher GPAs.B) If a student wishes to earn higher grades, he or sheshould get more sleep. C) Based on the pattern in the scatterplot and the cor-relation, these data indicate that as students sleep longer, they tend to earn lower GPAs. D) The scatterplot and the correlation coefficient contra-dict one another. E) The scatterplot shows two influential points thataffect the value of the correlation.
