Answer:
44 swimmers
Step-by-step explanation:
Given the data points :
66, 8) (71, 23) (72 16) (75 30) (78 35) (80 24) (82 37) (86 37) (87 42) (90 50)
Temperature X:
66
71
72
75
78
80
82
86
87
90
Number of swimmers Y:
8
23
16
30
35
24
37
37
42
50
Using the online regression calculator :
The regression model obtained is ;
ŷ = 1.5045X - 88.2056
Where
1.5045 = gradient or slope
-88.2056 = intercept
x = independent variable
y = dependent variable
Number of swimmers when temperature = 88
y = 1.5045(88) - 88.2056
y = 44.19
y = 44 (nearest whole number)
