A survey was conducted of two types of marketers. The first type being marketers that focus primarily on attracting business (B2B), and the second type being marketers that primarily target consumers (B2C).

The study also revealed that 313 (53%) of B2B marketers and 243 (60%) of B2C marketers commonly use a video social media tool. Suppose the survey was based on 589 B2B marketers and 407 B2C marketers. Complete parts (a) through (c) below. a. At the 0.05 level of significance, there evidence of a difference between B2B marketers and B2C marketers in the proportion that commonly use the business social media tool?

based on 589 B2B marketers and 407 B2C marketers. Complete parts (a) through (c) below.
a. At the 0.05 level of significance, is there evidence of a difference between B2B marketers and B2C marketers in the proportion that commonly use the business social media tool? Let population 1 correspond to B2B marketers and population 2
correspond to B2C marketers. Choose the correct null and alternative hypotheses below.
O A. Ho: T1 2 T2
B. Ho: T STh2
H1: Tq <Thz
H1: Tq > T2
C. Ho: Tq # T2
H1: Tq = T2
O D. Ho: T4 = T2
