Answer:
Explanation:
(a). By plotting the data on an Excel spreadsheet, the uploaded image below represents our findings
(b) The sample correlation coefficient is calculated using the Excel Correlation function as follows;
Admission Rate (%) 4-Year Graduation 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 calculated value of the sample correlation coefficient is = -0.76
This indicates that the two variables exhibit a moderately linear inverse correlation.
Cheers, I hope this is useful.
