Answer:
Explanation:
(a). plotting using Excel sheet, we have the picture uploaded below
(b) The sample correlation coefficient is also computed using Excel Correlation function, given thus;
Admit Rate (%) 4-Year Grad Rate (%)
44 73
71 62
29 89
39 86
66 55
28 73
54 63
10 88
26 84
43 77
76 71
67 68
6 86
66 59
81 66
18 88
31 71
9 84
15 86
8 88
17 84
56 62
51 79
54 68
75 50
13 86
40 70
67 68
41 47
68 71
∴ The value of the sample Correlation Coefficient is = -0.76
This tell us that the two variables are moderately linear inverse correlated.
cheers i hope this helps.
