    Resistive load bank testing for generator

    Resistive load bank for testing generators We have developed a resistive load bank 30 KWatts in our setup based on readings we have taken on different loads with different generators and maximum current rating observed was 36 Amperes at 0.8 Pwr Factor. Therefore, we designed our load bank...

    Graduate Lagraingian constrained optimization problem

    Im not sure if this is the right place, but I have an optimization problem where I assume we are supposed to use the Lagraingian method: Consider the labour supply problem for an individual over an entire year. Suppose the individuals utility is described by the function U = (C^0.5) x...

    Undergrad What is the Coefficient of Determination for Supermarket Sales Data?

    n = 12 (number of stores) k = 1---> one independent variable, one dependent (I can asume single regression) also, its r^2 because its a sample

    Undergrad What is the Coefficient of Determination for Supermarket Sales Data?

    Ive been posting many questions, hopefully the alst for awhile: You have collected data on sales and population within a one mile radius on 12 stores of a supermarket. You determined that the adjusted coefficient of determination is 93.85%. Determine the coefficient of determination. I...

    Undergrad What is the coefficient of correlation between sales and price?

    In a sample of 21 observations obtained it was found that sales and price have an inverse relationship and coefficient of determination is 106% as much as the adjusted coefficient of determination. It is also known that the variance of sales around mean is 640. What is the coefficient of...

    Undergrad Least squares regression problem

    Hi, I am having some difficulty with this problem: what would be Y^h^a^t if s_y_/_x = 439, n = 24 and 95% confidence interval estimate for the average Y given a particular value of X is 1125 and 1695. ----------------- I know Y^h^a^t = b_o + b_1x but I am not sure how I can use the...
