Assume that for dry rice and beans 20 cups = 1 basin
40 basins = 1 sack
a. A sack contains 100 mg of rice in 1 basin. Estimate the number of grams of rice in 1 cup.
b. A trader buys a sack of rice for N6,000 and sells it at N200 per basin. Estimate the profit on a sack of rice.
c. A trader charges N5,000 for a sack and N140 for a basin of beans.
Four women buy a sack of beans between them. They share the beans equally.
How many basin does each woman get ?
How much does each woman save by buying the beans in this way?

1. the manager of collins import autos believes the number of cars sold in a day (q) depends on two factors: (1) the number of hours the dealership is open (h) and (2) the number of salespersons working that day (s). after collecting data for two months (53 days), the manager estimates the following log-linear model: q 4 equation 1 a. explain, how to transform the log-linear model into linear form that can be estimated using multiple regression analysis. the computer output for the multiple regression analysis is shown below: q4 table b. how do you interpret coefficients b and c? if the dealership increases the number of salespersons by 20%, what will be the percentage increase in daily sales? c. test the overall model for statistical significance at the 5% significance level. d. what percent of the total variation in daily auto sales is explained by this equation? what could you suggest to increase this percentage? e. test the intercept for statistical significance at the 5% level of significance. if h and s both equal 0, are sales expected to be 0? explain why or why not? f. test the estimated coefficient b for statistical significance. if the dealership decreases its hours of operation by 10%, what is the expected impact on daily sales?
