Suppose we want to see if there is evidence of difference between A, B, and C in the proportion of Level 1. A B C Total Level 1 10 30 50 90 Level 2 40 45 50 135 Total 50 75 100 225 a) At significant level 5%, test the equality of proportion of Level 1 for category A, B and C. b) If needed, perform the Marascuilo procedure for pairwise comparisons

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 !
