Batch 3 - May I please get guidance/help with the following homework problems? Thank you for your help.

11.m is an example of a

a.population parameter

b.sample statistic

c.population variance

d.mode

12.The mathematical equation relating the independent variable to the expected value of the dependent variable; that is, E(y) =₀+₁x, is known as

a.regression equation

b.correlation equation

c.estimated regression equation

d.regression model

13.A regression analysis between sales (in $1000) and price (in dollars) resulted in the following equation: = 60 - 8X

The above equation implies that an

a.increase of $1 in price is associated with a decrease of $8 in sales

b.increase of $8 in price is associated with a decrease of $52,000 in sales

c.increase of $1 in price is associated with a decrease of $52 in sales

d.increase of $1 in price is associated with a decrease of $8,000 in sales

14.Regression analysis was applied between sales (in $1000) and advertising (in $100) and the following regression function was obtained: = 500 + 4 X

Based on the above estimated regression line if advertising is $10,000, then the point estimate for sales (in dollars) is

a.$900

b.$900,000

c.$40,500

d.$505,000

15.If a hypothesis is rejected at 95% confidence, it

a.will not be rejected at 90% confidence

b.will also be rejected at 90% confidence

c.sill sometimes be rejected at 90% confidence

d.none of these alternatives is correct
