Suppose a study is conducted using only Boeing 737s traveling 800Kms oncomparable routes during the same season of the year. Can the number ofpassengers predict the cost of flying such routes? It seems logical that morepassengers result in more weight and more baggage, which could, in turn, result inincreased fuel consumption and other costs. Suppose the data displayed in thetable below are the costs and associated number of passengers for twelve 800-kmscommercial airline flights using Boeing 737s during the same season of the year.We will use these data to develop a regression model to predict cost by number ofpassengers. A plot of the data collected is shown in Figure 3.Cost600550500450400350300566778Number of Passengers89910Figure 3: Scatter plot of number of passengers on the x-axis andCost on the y-axis.a) Describe the relationship between number of passengers and Cost based on Figure3.

From the above scatter plot We can seen that if the one variable is increase then the other…

The blue catfish (Ictalurus Furcatus) is the largest species of North Amercian catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to Amercian Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 50 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n=50; ¯x=40.72 pounds; s=5.03pounds Calculate your test statistic.

A Midwest college admissions committee recently conducted a study to determine the relative debt incurred by students receiving their degrees in four years versus those taking more than four years. Some on the committee speculated a four-year student would likely be attending full time, whereas one taking more than four years could have a part-time job. However, average total debt provides only part of the information. Since the average, or mean, is affected by both large and small values, the committee also needed some way to determine the relative variances for the two groups. Samples of size 20 produced standard deviations of 2,636 for four-year graduates and 1,513 for those taking more than four years. Conduct a test of hypothesis to determine if the standard deviation of the debt for four-year graduates is larger than those taking more than four years. Use a significance level of 0.05.

6. Assume that the scatterplot shows the median volume and median value of used cars over the years in the UK used car market. (a) As the data are graphed, which is the independent and which is the dependent variable? (b) Why do you suppose median value and volume have been used instead of the mean? (c) Using the graph, estimate the median value of sales if the median volume of used cars sold is 2.3 million. (d) Use the equation to predict the median value of sales if the median volume of used cars sold is 2.3 million.

The following regression equation is based on the analysis of four variables: SM_DOLLARS is the dollar amount of a watershed conservation agency's weekly spending on social media ads. RADIO_ADS is the number of radio advertisements aired weekly by the agency. WS_DOLLARS is the dollar amount of the agency’s weekly spending on web search ads. The variable WEB_VISITS is the number of weekly visitors to their educational website. These data have been recorded every week for the past three years. WEB_VISITS (expected) = 109 + 0.2*SM_DOLLARS + 1.5*RADIO_ADS + 1.1*WS_DOLLARS The data meet the assumptions for regression analysis, and the regression results, including the coefficients, were found to be statistically significant. How many additional weekly web visits would you predict when the agency increases its weekly spending on social media ads by $150 without changing the amount spent on radio ads or web search ads? (Round your answer to the nearest whole number.)

An important factor for used car buyers when determining the value of a car is how far the car has been driven. To examine this, a used car dealer randomly selects 50 five-year-old Kia Sportage cars that have been sold at auction during the past month. Each car was in top condition and equipped with automatic transmission, GPS and air conditioning. The following Microsoft Excel output analysis of these data shows the price ($'000) and the number of kilometres ('000Km) on the odometer. Use these results to answer the questions on the next page.
