A new company is in the process of evaluating its customer service. The company offers two types of sales: (1) Internet sales and (2) store sales. The marketing research manager believes that the Internet sales are more than 10 percent higher than store sales. The alternative hypothesis for this problem would be stated as Multiple Choice PInternet \( -P_{\text {store }}>0 \).

The alternative hypothesis you're looking for involves testing the difference between the proportions of Internet and store sales. In this scenario, if the manager believes that Internet sales are more than 10 percent higher than store sales, the hypothesis can be formulated as \( P_{\text{Internet}} - P_{\text{store}} > 0.10 \). This means the manager expects the proportion of Internet sales to exceed that of store sales by more than 10%. In practical terms, this evaluation can guide strategic decisions. If the Internet sales indeed show a significant difference, the company might focus on enhancing its online presence or executing targeted marketing campaigns to boost sales further. Conversely, if results do not support the hypothesis, they may reconsider their sales strategy for both channels.
