A used car salesman wants to be able to predict the resale value of a car based on the age of the car. What type of variable is
Feliz [49]

Answer:

D. Cannot be determined without seeing the data.

Step-by-step explanation:

Option “D” is correct because age is a quantitative variable but if we look at the exact number or exact age of the car then the car’s age is quantitative discrete but if we look at the age of the car by going a number of years then it will be continuous. Therefore, without getting the exact information of the age of the car we cannot predict the type of variable. So the option “D” best fit for the answer.

bonufazy [111]

Answer:The required interval is (0.196, 0.030).

Step-by-step explanation:

Since we have given that

n = 432

x = 108

So, \hat{p}=\dfrac{x}{n}=\dfrac{108}{432}=0.25

at 99% level of confidence, z = 2.576

So, Margin of error would be

z\times \sqrt{\dfrac{pq}{n}}\\\\=2.576\times \sqrt{\dfrac{0.25\times 0.75}{432}}\\\\=2.576\times 0.021\\\\=0.0536

So, margin of error = 0.0536

Now, confidence interval would be

\hat{p}\pm 0.0536\\\\=(0.25-0.0536,0.25+0.0536)\\\\=(0.1964,0.3036)\\\\\approx (0.196,0.030)

Hence, the required interval is (0.196, 0.030).
