You are interested in purchasing a new car. One of the many points you wish to consider is the resale value of the car after 5 y

gulaghasi [49]

Answer:

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

(11,688.68 , 12,511.32)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 17

mean of the sample x⁻ = 12,100

Standard deviation of the sample (S) = 800

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

Step(ii):-

Degrees of freedom ν =n-1 = 17-1 =16

$t_{(16 , 0.05)} = 2.1199$

The 95% confidence interval for the true mean resale value of a 5-year-old car of this model

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} } )$

$(12,100 - 2.1199\frac{800}{\sqrt{17} } , 12,100 + 2.1199 \frac{800}{\sqrt{17} } )$

(12,100 - 411.32 , 12,100 + 411.32)

(11,688.68 , 12,511.32)

If you think about it it is just greatest common factor.

the factors of 12 are 1, 2, 3, 4, 6, 12

The factors of 15 are 1, 3, 5, 15
