A random sample of 863 births included 429 boys. Use a significance level of 0.05% to test the claim that 50.8% of newborn babies are boys. Do the results support the belief that 50.8% of newborn babies are boys?

what is all that apply?

step-by-step explanation:

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

hope this you
