Answer:
y = 0.28X - 0.77
Step-by-step explanation:
Given the data :
X:
40
32
38
21
у:
10
8
10
5
Equation of regression line is in the form:
y = mx + c
Where y = predicted variable ;
c = intercept ; m = slope or gradient ; x = predictor variable
Using The correlation Coefficient calculator :
The regression equation obtained is :
ŷ = 0.2754X - 0.77028
Rounding values in our regression output to 2 decimal places :
y = 0.28X - 0.77
Hence best model to make prediction :
y = 0.28X - 0.77
Answer:
The answer is 260 days.
Step-by-step explanation:
120 Men - 195 days (provision left after 5 days)
30 men left the fort
Men left - 90 Days - D
so 120 x 195 = 90 x D
D= 260 days
