An automotive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. step 2 of 2 : suppose a sample of 1418 new car buyers is drawn. of those sampled, 354 preferred foreign over domestic cars. using the data, construct the 99% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars. round your answers to three decimal places.

99% confidence interval would be (0.13,0.26).

Step-by-step explanation:

Since we have given that

Sample size n = 1418

x = 354

So,

At 99% level of significance, z = 2.58

So, interval would be

Hence, 99% confidence interval would be (0.13,0.26).

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal
