QUESTION 36 Consider a linear regression model that examines the relationship between income (in thousands of dollars) and education level (in years) on job satisfaction (on a continuous scale of 1 to 10). The model includes an interaction term between income and education level. Which of the following interpretations of the interaction term coefficient is correct in this context? O None of these For each additional year of education, the increase in job satisfaction is $1000. The interaction term helps to eliminate the influence of outliers in the data. O The impact of income on job satisfaction depends on the level of education. O The interaction between income and education level statistically significantly influences job satisfaction.

QUESTION 1 a. (3 points) Write a declaration for the array below and name it matrix. -1 7 1 1 2 -1 5 4 1 3 -1 6 b. (5 points) Given the contents of matrix above, write a program segment (NOT THE ENTIRE PROGRAM) that will print the elements of the array as well as the column and row totals. Do not worry about drawing the lines in the table. Example: -1 7 1 1 2 -1 5 4 1 3 -1 6 Total = 8 Total = 12 Total = 7 Total = 7 Total = 2 Total = 10 Total = 8 c. (5 points) Pretend you don't know the contents of the array. Write the program segment (NOT THE ENTIRE PROGRAM) that will print out all elements of matrix that are positive.

5. [15 Marks] A cast steel structure is made of a rod of square section 2.5cm×2.5 cm as shown in figure 1. What is current that should be passed in 500 turn coil on the left limb so that a flux of 3 mWb is made to pass in right limb. Assume permeability as 700 and neglect leakage. I A N=500 40.sm 40.cm 25 cm 3mWb Figure 1 Q2. (CLO 2) [15 Marks] P.H-S-L A single phase 50 Hz, 50 KVA, 2400V/120V transformer gave following test results: Open circuit test: 120 V, 9.85 A, 396 $W_1$ (L.V side instruments) Short circuit test: 92 V, 20.8 A, 810 W (H.V side instruments) Calculate: a) Efficiency at rated KVA and 0.8 power factor lagging 3.2% b) Voltage regulation at rated KVA and 0.866 power factor lagging 3.25 ? Q3. (CLO 2) [10 Marks] A wave wound 6 pole, long shunt compound dc generator has 600 armature conductors. The generator is driven at 300 r.p.m.. Calculate emf generated if the flux per pole is 0.060 Wb. If now the generator is required to produce emf of 550 V at a reduced value of flux/pole of 0.055 Wb, calculate the speed at which armature of generator must be drive.
