Answer:
(1) Please find attached the graph of the data
(2) 160.396 m
(3) The correlation that exist is a straight line correlation
Step-by-step explanation:
The given data are;
Distance, Time
(m), (s)
50, 6.1
100, 12
150, 18.3
200, 25.2
250, 31.7
(2)
Based on the linear regression formula, we have;




The line is
y = 7.7581×x+5.234
When t = 20 s, we have
y = 7.7581*20+5.234 = 160.396 m
(3) The correlation that exist is a straight line correlation
