Answer:
[ -0.13, -0.15 ] ( D )
Explanation:
Given data :
sample size ( n ) = 50
Independent variable ( p ) = 1
<u>determine the confidence interval for the slope </u>
Df ( degree of freedom ) = n - p - 1 = ( 50 - 1 - 1 ) = 48
b ( estimated slope ) = -0.23
Standard error of slope = 0.04
confidence interval = 95%
For confidence interval of 95% and Df of 48 ; critical value ( t ) = 2.011
∴ Confidence interval
= -0.23 ± ( 2.011 * 0.04)
= -0.23 ± 0.08044
= [ -0.13, -0.15 ]
Answer:
Make $200,000 in less than two month (Send me a message if interested)
If I told you that you could turn your spare time into a side-income online business, would you be interested?
I recently became introduced to two guys that were able to make $960,824.41 within 31 days. These guys are “anti-gurus”... they’re everyday guys. Their students have generated millions, too. And they also helped me to make over $200,000 in less than 2 months
I was able to convince them to show you how they did it on a free training event this week.
They’re sharing this for the first time and will show you how to turn your spare time into a $100,000.00 online side business.
The best part? You can do this with NO experience / technical skills.
Explanation:
The statement that must be true about the demand for a product if it is inelastic is that, a price increase does not have a significant impact on buying habits. The correct answer would be option B. When the demand is inelastic, this situation means that the demand for a product does not decrease nor increase in corresponds to the rise or fall of its price.

Hope this helps! I got it correct also so I know its correct!
Answer:
After tax cost of debt is 4.16%
Explanation:
The yield on the debt which is pre-tax cost of debt can be computed using the rate formula in excel, which is given as follows:
=rate(nper,pmt,-pv,fv)
where nper is the number of coupon payments,this is calculated as 19*2 since it has a semi-annual coupon interest
pmt is the periodic coupon payment 6.1%/2*$2000=$61
pv is the current price of the bond which is $1933
fv is the face value repayable on redemption $2000
=rate(38,61,-1933,2000)
=3.20%
This is semi-annual yield , annual yield is 3.20%*2=6.40%
After tax cost of debt=6.40%*(1-t)
where t is the tax rate at 35%=0.35
after tax cost of debt=6.40%*(1-0.35)
=4.16%
