In the Parent-Teen cell Phone Survey conducted by Princeton Survey Research Associates International, 800 randomly sampled 16-17-year-olds living in the US were asked whether they have ever used their cell phone to text while driving. Of the 800 teenagers surveyed, 272indicated that they text while driving. Obtain a 95% confidence interval for the proportion of 16-17-year-olds who text while driving.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
