two years ago, you created goforless, a new app that shows people the cheapest way to travel by bus, train, or air between two cities. turns out that your app was a big success, and now you’ve made enough money to hire some additional employees. you’re trying to figure out what your new employees should do. what kinds of jobs should they have? how should they work together? how should they work with you? how can you give your employees enough freedom to be innovative, while maintaining enough control over their work to be sure that goforless will stay true to its overall goals?

Alarge university wanted to study the relationship between completing an internship during college and students' future earning potential. prom the same graduating class, they selected a random sample of 80 students who completed an internship and 100 students who did not complete an internship and examined their salaries five years after graduation. they found that there was a statistically higher mean salary for the internship group than for the noninternship group. which of the following interpretations is the most appropriate? a. there could be a confounding variable, such as student major, that explains the difference in mean salary between the internship and no internship groups.b. we cannot infer anything from these data since the distribution of salaries is likely right skewed.c. you cannot draw any valid conclusions because the sample sizes are different.d. more students should complete internships because having an internship produces a higher salary.
