b) Data was collected on 344 corporate executives to find out the effect of MBA degree and work experience on their salary. The following model was estimated: Y = 2.3501 + 3.6306D11 – 2.6354 D2i + 0.8527 X¡ + 1.634 (D, * X)i (2.1805) (- 3.457) (1.263) (7.605) (2.98) R? = 0.8968 Y: Annual Income in Lakhs of Rupees Di and D2 are MBA and gender dummies respectively X: Work experience in years DI = 1 if one has MBA degree = 0 otherwise D2 = 1 for a female executive = 0 for a male executive i. Write the regression equations for female MBA executives and male MBA executives separately. ii. Find the mean income level for the reference category and interpret it. iii. Test the statistical significance of differential intercept coefficient between female MBA executives and Male MBA executives at 5% level of significance. iv. Interpret the coefficient of D,*Xi.

Sales of fine-cut cigarettes (in millions) in a country are given by y = - 14.898x + 356.467x + 5332.618, where x is the number of years after 1980. During what years does this model indicate that sales would be at least 6 billion? The sales are at least 6 billion for the years through (Round up to the nearest year as needed.)

A manufacturer estimates that when x units of a particular commodity are sold domestically and y units are sold tiv sl to foreign markets, the profit is given by P(x, y)=(x-30)(70+5x– 4y)+(y-40)(80-6x+7y) hundred dollars. If monthly domestic sales vary between 100 and 125 units and foreign sales between 70 and 89 units, what is the average monthly profit?

5.3 Determine the real root of f(x) = -25 + 82x – 90x² + 44x³ – 8x* + 0.7x: (a) Graphically. (b) Using bisection to determine the root to ɛ, = 10%. Employ initial guesses of xị = 0.5 and x, = 1.0. (c) Perform the same computation as in (b) but use the false- position method and ɛ, = 0.2%.

An advertising firm is hired to promote a new television show for 3 weeks before its debut and 2 weeks afterward. After t weeks of advertisement campaign, it is found that P(t) percent of the viewing public is aware of the show, where P(t) = (59t/0.7t^2+16) + 6 a. What is the average percentage of the viewing public is aware of the show during the 5 weeks of advertising campaign? (Hint: P(0) is already in the unit of percent) b. At what time during the first 5 weeks of the campaign is the percentage of viewers is the same as the average percentage found in part (a)? (Hint: use algebra or graph to solve the problem
