Suppose you want to accumulate $120,000 for your retirement in 30 years.
Consider these two plans:
Plan A: make a single deposit into an
account with an annual compounding and
an APR of 5%.
Plan B: Make a single deposit into an account with continuous compounding and
an APR of 4.8%
1.) how much do you need to deposit in
each amount in order to reach the goal?
2.) calculate the current APR the
compounding period, and the claimed APY
for your personal savings account. (Or pick
a rate from a nearby bank)
3.) calculate the APY on your account (or
someone u know)
4.) Does your calculation agree with the
APY claimed by the bank?

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?
