Your work at a company that sells 'Green' cars. You are interested in what proportion of your cars have mpg of 100 or more. In a sample of 25 green cars, 7 of them have mpg of 100 or more. Calculate a 95% confidence interval for the proportion of cars that have mpg of 100 or more. 1. Calculate p-tilde, the initial estimate for the proportion of cars with mpg of 100 or more.

answer: 2530

hope this

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
