- Required Information [The following information applies to the questions displayed below.] Davis Stores sells clothing in 15 stores located around the southwestern United States. The managers at Davis are considering expanding by opening new stores and are interested in estimating costs in potential new locations. They believe that costs are driven in large part by store volume measured by revenue. During a discussion, one of the managers suggests that number of employees might be better at explaining cost than store revenues. As a result of that suggestion, managers collected the following information from last year's operations (revenues and costs in thousands of dollars): Store 101 182 103 184 105 Req D1 106 107 108 109 110 111 112 113. 114 115 Intercept Employees Costs $5,740 3,565 5,600 4,327 3,689 2,777 2,821 2,318 2,124 3,090 2,329 5,973 5,257 3,220 5,411 Req D2 Employees 51 49 51 35 38 26 35 37 24 29 28 56 53 53 50 Revenues $2,724 5,096 5,183 2,240 5,519 2,846 3,349 6,340 3,646…A researcher takes a sample of 40 introverts and 40 extroverts and asks them to solve problems in either a crowded room or an uncrowded room. The researcher measures the number of problems solved (numbers can range from 0 problems solved to 25 problems solved). Here are the results Crowded Room Uncrowded Room Introverts M = 12 M = 18 Extroverts M = 18 M = 12 Does there appear to be a main effect of room? Does there appear to be a main effect of personality (introversion/extraversion)? Does there appear to be an interaction between room and personality?Answer with clear explanation.
