Step-by-step explanation:
The guidelines for interpreting correlation co-efficient r are :
1. Strong correlation 0.7<|r|≤1
2. Moderate correlation 0.4<|r|<0.7
3. Weak correlation 0.2<|r|<0.4
4. No correlation 0≤|r|<0.2
Logarithmic regression
(i). Mean :
(ii) Trend line :
(iii). Correlation coefficient :
Now using the technology we can calculate
The equation of the regression curve is y = A + B(lnx)
we get A = 30.72 , B = 17.19
The equation of regression curve is = 30.72 + 17.19(lnx)
