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). It was reported that 518 (88%) of B2B and 246(59%) of B2C marketers commonly use a business social media tool. The study also revealed that 301(51%) of B2B marketers and 248(59%) of B2C marketers commonly use a video social media tool. Suppose the survey was based on 590 B2B marketers and 420
B2C marketers. Complete parts (a) through (c) below.
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.
Part 2
