    Ashish,

    You are right. I have taken the following equation:
    Sales = -180 + 6.09 * (T) + 1.05 PS + 0.00015 * GDP
    and plugged in:
    Temperature in Summer = 42 degree Celsius
    Prior year sales = 3000 million Rupees
    Nominal increase in GDP = 6600X1000 million Rupees

    The answer is: 4395.78 ~ 4396 i.e. B

    Q6 Ans B:

    First find out R squared which is equal to SSR/SST

    R squared = 6000/7000 = 0.857
    (1 – RadjXRadj) = (1 – RXR) * (n-1)/(n-k-1)
    = (1-0.857) * (18-1)/(18-3-1) = 0.143 * 17/14

    Adjusted R square = 0.8263

    The most likely value of variable A in the ANOVA table is:

    a)3

    There are three independent variables explaining the variation in the dependent variable.

    I agree with Ashish.

    Here, df = k = 3

    I agree with Ketan. The answer is B or 14.

    I was looking forward to revision on other topics also.

    Q8 Ans B:

    The degree of freedom for residual item in the ANOVA table is equal to n-k-1,
    where n is the number of observation
    k is the number of independent variables
    For the total item degree of freedom is n-1, since the value is given as 17 => n =18
    Hence degree of freedom for residual will be n-k-1 = 18-3-1 = 14
