The is an inferential statistic used to determine the number of standard deviations in a t distribution that a sample mean deviates from the mean value or mean difference stated in the null hypothesis.

the answer to your question would the T statistic

The function is y = 17000 + 820 x

where: y = price of the car.

x = time in years.

After 3.3 years, the car will cost $19706.

Step-by-step explanation:

Hi there!

Let y be the price of the car.

After the first year, the price of the car will be:

y = 17000 + 820

After the second year:

y = 17000 + 820 + 820 or 17000 + 820(2)

After the third year:

y = 17000 + 820 + 820 + 820 or 17000 + 820(3)

Then, after x years:

y = 17000 + 820 x

After 3.3 year, the car will cost:

y = 17000 + 820(3.3) = 19706

After 3.3 years, the car will cost $19706.
