The time taken to arrive at the fire is critical. This raises the question, Should insurance companies lower premiums if the home to be insured is close to a fire station? To help make a decision, a study was undertaken wherein a number of fires were investigated. The distance to the nearest fire station (in miles) and the percentage of fire damage were recorded.

- HELP!!! PLZRequired 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…IG SYSTEM (ACADEMIC) ss Statistics 1 (section50) | Mode can be used either numerical or categorical data Select one: CTrue O False PAGE

If yes, state whether the area could represent the p-value for a one-sided or a two-sided alternative hypothesis. (images are the graphs)Experimental Methods - Question 30 The particular question is related to Lean Six Sigma Black Belt (MindPro) covering Experimental Methods. Please thoroughly understand the relevant image, and accurately confirm whether the mentioned statement is TRUE or FALSE, by, clearly providing a Justification/Working.Question 19 Lucille, Rocio, and Cristina are all taking College Mathematics but from different professors. They all recently took a statistics exam and the exam scores were normally distributed in each of their classes. • Lucille's class had an average grade of 77 and the standard deviation was 4. Lucille earned 84.2 on the exam. Rocio's class had an average grade of 85 and the standard deviation was 3. Rocio earned 85.6 on the exam. Cristina's class had an average grade of 85 and the standard deviation was 5. Cristina earned 91.5 on the exam. Since some professors give harder exams than others, these students decided to use statistics to figure out who did the best on their exam. Use the Cumulative Z-Score Table to answer the following questions. Write your answers as a percent with two decimal places. Hint • Lucille's score places her above % of her class. % of her class. Rocio's score places her above % of her class. • Cristina's score places her above Which person has the highest…
