    Hi guys and gals

    I was wondering if someone could help me with a regression question, Im hoping to get a general direction on it, please see below thanks

    sales experience age employees
    17 2 23
    23 6 33
    20 8 30
    18 11 35
    19 4 24
    22 7 49
    21 7 36
    28 14 40
    26 12 46
    12 3 51

    a) What is the estimated Regression Equation?




    b) Interpret the coefficient on X1 and X2

    c) State whether or not there is a significant relationship between sales and both explanatory variables, taken together, at the 5% level of significance.

    d) State whether or not the explanatory variables X1 and X2 are statistically significant at the 5% level. Be sure to state the null and the alternative hypothesis and on what your conclusions are based.
