Does co-browsing have positive effects on the customer experience? Co-browsing refers to the ability to have a contact center agent and customer jointly navigate an online document or mobile application on a real-time basis through the web. A study of businesses indicates that 73 of 120 co-browsing organizations use skills-based routing to match the caller with the right agent, whereas 93 of 179 non-co-browsing organizations use skills-based routing to match the caller with the right agent. Complete parts (a) and (b) below. a. At the 0.01 level of significance, is there evidence of a difference between co-browsing organizations and non-co-browsing organizations in the proportion that use skills-based routing to match the caller with the right agent? State the null and alternative hypotheses, where it, is the population proportion of co-browsing organizations that use skills-based routing and it is the population proportion of non-co-browsing organizations that use skills-based routing.

Round to two decimal places as needed. Use a comma to separate answers as needed.) State the conclusion. the null hypothesis. There is evidence to support the claim that there is a difference between co-browsing organizations and non-co-browsing organizations in the proportion that use skills-based routing to match the caller with the right agent. b. Find the p-value in (a) and interpret its meaning. The probability of getting a test statistic the sample result, given that Ho is true, is approximately]. Type an integer or a decimal.
