USING R STUDIO we determined the Correlation between two variables (x=12kg and y=5kg ).
Pearson’s product-moment correlation
data: GAS_PRICES_X$`5kg` and GAS_PRICES_X$`12kg`
t = 4.0677, df = 2, p-value = 0.05546
alternative hypothesis: true correlation is not equal to 0
95 percent confidence interval:
-0.1794232 0.9988688
sample estimates:
cor
0.9445419
From the analysis above we are able to determine that there is a strong positive relationship between (x=12kg and y=5kg ) Prices.
USING R STUDIO we determined the regression model as well as predictive patter of the two variables (x=12kg and y=5kg ).
RESULTS:
cor.test(GAS_PRICES_X$`5kg`,GAS_PRICES_X$`12kg`)
Call:
lm(formula = GAS_PRICES_X$`5kg` ~ GAS_PRICES_X$`12kg`)
Coefficients:
(Intercept) GAS_PRICES_X$`12kg`
137.0304 0.5079
where;
Bo = 137.0304
B1 = 0.5079
y = 137.0304 + 0.5079x
Thus if y = 2,073.41 then
2073.41 = 137.0304 + 0.5079x
x= 3,812.52
NOTE: If x is 0 that is if the 12kg price is 0 then y 5kg is 137.0304 naira
