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)

Answers

Answer:

see below

Explanation:

It is a requirement that all drivers purchase auto insurance. However, not all drivers oblige to this requirement. This is a certain percentage of drivers without any form of auto insurance.  

Uninsured motorists is an insurance policy that offers insurance protection for bodily injury in an accident caused by an uninsured motorist. Some uninsured motorist policies may cover damages to properties. Therefore, uninsured motorist insurance is important because it allows one to claim compensation from their own insurances if they are involved in an accident caused by a negligent uninsured motorist.

Timothy Carter has net monthly income of $3,800. He has a monthly auto loan payment of $350, a student loan payment of $150, a mortgage payment of $1,200, and a credit card minimum payment of $45. What is his debt-payments-to-income ratio

Answers

Answer:

45.9%

Explanation:

The computation of the debt payment to income ratio is as follows:

Income = $3,800

And,

Debt payment is

= auto loan payment + student loan payment +mortgage payment + credit card payment

= $350 + $150 + $1200 + $45

= $1745

So,  

Debt payment to income ratio is

= Debt payment ÷  income

= $1,745 ÷ $3,800

= 0.459

= 45.9%
