A consumer magazine has contacted a simple random sample of 58 owners of a certain model of automobile and asked each owner how many defects had to be corrected within the first 2 months of ownership. The average number of defects was 4.9 with a sample standard deviation of 2.1 defects. Construct the 90% confidence interval for the population mean.

Answers

Answer 1

Answer:

(4.439 ; 5.361)

Explanation:

Given :

Confidence level = 90%

α = (1 - 0.9) / 2 = 0.05

Sample size (n) = 58

Degree of freedom (df) = n - 1 = 58 - 1 = 57

Mean number of defect (m) = 4.9

Standard deviation (s) = 2.1

m ± t0.05, 57 * (s /√n)

t0.05, 57 = 1.672029 (t value calculator)

4.9 ± 1.672 * (2.1 /√58)

4.9 ± 0.4610431

4.9 - 0.4610431 ; 4.9 + 0.4610431

(4.4389569 ; 5.3610431)

(4.439 ; 5.361)

Explain why the Federal Reserve Bank might be concerned if the economy begins growing too quickly.

Answers

Answer:

To check against high inflation rate

Explanation:

Inflation is the steady increase in the prices of goods and services in the economy per period. Inflation is associated with economic growth. Naturally, as the economy grows, the prices of different products and services tend to increase.

When the economy is growing at a fast rate, the inflation rate tends to increase.  A rise in the inflation rate means prices are increasing at a high rate. When prices are unstable, planning and budgeting become challenging for individuals, firms, and the government. Inflation erodes the strength of a currency, which causes unstable prices and other economic challenges. The Federal Reserve keeps monitoring inflation and applies appropriate monetary policies to regulate economic growth and the inflation rate.

A coupon bond which pays interest semi-annually, has a par value of Rs.1,000, matures in 5 years, and has a yield to maturity of 8%. If the coupon rate is 10%, the intrinsic value of the bond today will be __________.

Answers

Answer:

Rs.1,081.10  

Explanation:

The intrinsic value of the bond today is the present value of the bond's future cash flows discounted at the appropriate yield which in this case is the semiannual yield to maturity since the bond pays coupons twice a year.

Using the bond price formula below, the bond price is computed thus:

Bond price=face value/(1+r)^n+semiannual coupon*(1-(1+r)^-n/r

face value=Rs.1,000

r=semiannual yield to maturity=8%*8/12=4%

n=number of semiannual coupons in 5 years=5*2=10

semiannual coupon=face value*coupon rate*6/12=1000*10%*6/12=50

bond price=1000/(1+4%)^10+50*(1-(1+4%)^-10/4%

bond price=1000/(1.04)^10+50*(1-(1.04)^-10/0.04

bond price=1000/1.48024428 +50*(1-0.67556417 )/0.04

bond price=1000/1.48024428 +50*0.32443583 /0.04

bond price= 675.56+405.54 = Rs.1,081.10
