Your younger brother, a fourth form practical geography student wishes to test whether there could be some relationship between annual visits to a local market by all residents surrounding that market. After a well-designed field study he obtains the following figures: Number of visits per year 21 13 19 18 17 17 14 20 10 11 Residence distance from market (KM) 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 From the information above, what is the dependent variable and what is the explanatory variable? Using (i) above, obtain the regression equation of Yi on Xi. Hence, estimate the residence distance from the market (in KM) if the number of visits are 16 visits Sketch your results in (ii) above. What conclusion can you draw from your sketch?

For the following line graph, State at least one type of conclusion that could be made from the data provided for the KPI. Suggest one other data source that would provide more information to make data-driven decisions. Explain what information that source would supply. I used the line graph btw. Examples: 1)The KPI webpage for South Texas College provides information on the proportion of graduates who find employment. According to the data, over the past five years, the proportion of graduates who find work has risen annually. Data on the percentage of students who are employed in their field of study after graduation, the percentage of students who are employed full-time after graduation, and the percentage of students who are satisfied with their job after graduation would also be useful in making decisions about post-graduation success. This information would shed light on the factors that are causing the rise in the proportion of graduates who find employment. 2)The…
You may need to use the appropriate technology to answer this question. Periodically, customers of a financial services company are asked to evaluate the company's financlal consultants and services. Higher ratings on the client satisfaction survey indicate better service, with 7 the maximum service rating. Independent samples of service ratings for two financial consultants are summarized here. Consultant A has 10 years of experience, whereas consultant B has 1 year of experience. Use a = 0.05 and test to see whether the consultant with more experience has the higher population mean service rating.

Identify several types of manufacturing companies for which process costing would be an appropriate product-costing system. What characteristics do the products of these companies have that would make process costing a good choice? How is process costing similar and different in a second or later processing department?
Martha’s Vineyard Marine Supply is a wholesaler for a large variety of boating and fishing equipment. The company’s controller, Mathew Knight, has recently completed a cost study of the firm’s material-handling department. Knight used work measurement to quantify the department’s activity. The control factor unit used in the work-measurement study was hundreds of pounds of equipment unloaded or loaded at the company’s loading dock. Knight compiled the following data. 1. Construct an Excel spreadsheet and use the Excel commands to perform a least-squares regression. Estimate the variable- and fixed-cost components in the company’s material-handling department costs. Note: Round the Variable-cost component to 2 decimal places and the Fixed-cost component to the nearest whole dollar amount. Fixed-cost component = Variable-cost component =

Large companies typically collect volumes of data before designing a product, not only to gain information as to whether the product should be released, but also to pinpoint which markets would be the best targets for the product. Several months ago, I was interviewed by such a company while shopping at a mall. I was asked about my exercise habits and whether or not I'd be interested in buying a video/DVD designed to teach stretching exercises. I fall into the male, 18 - 35-years-old category, and I guessed that, like me, many males in that category would not be interested in a stretching video. My friend Holly falls in the female, older-than-35 category, and I was thinking that she might like the stretching video. After being interviewed, I looked at the interviewer's results. Of the 94 people in my market category who had been interviewed, 14 said they would buy the product, and of the 108 people in Holly's market category, 34 said they would buy it. Assuming that these data came…
