ECMT 1010 Economics and Business Statistics A Assignment 1, 2010 Question 1: (a) pretend a table showing pertinent sum-up statistics for the terminate qualification of all vehicles. Briefly discuss the relevant aspects of your findings. add-in 1: Both Auto and Manual Models Fuel cleverness (L/100km) Mean7.632657498 m angiotensin converting enzymetary bar Error0.170608732 Median7.709114704 Mode8 Standard Deviation1.525970889 Sample Variance2.328587155 Kurtosis-0.451538264 Skewness-0.001472956 Range6.78524281 minimal4.71475719 Maximum11.5 Sum610.6125998 Count80 As it eatage be seen in table 1, the mean of the give the transmutation efficiency for simple machine and manual political machines is 7.63 L/100km. The fuel efficiency for all automobiles end range amidst a minimum repute of 4.71 L/100km and a maximum value of 11.50 L/100Km. This info can also be seen to near a normal dispersal as there is exceedingly miniature positive skewness shown (0.0015). The standard divergency, which indicates how much variability there is from the mean, is equal to 1.53 L/100km. Dispersion of 1 standard deviation contracts approximately 68% of the values, where 2 standard deviations contain 95% of the values. As this data represents a standard deviation of 1.53 L/100km it lies in between these percentages.

(b) Draw the most attach plot to visualize if car tilt has any relate on fuel efficiency. gabfest on your findings. Graph 1: Auto Cars and Manual Cars Yes it is plain from Graph 1 that weight has an effect on fuel efficiency. There is a rel atively strong positive race between the tw! o variables. accordingly with a certain fall of increase of the variable x (weight), the y variable (Fuel Efficiency) pass on also increase. In this case if weight is equal to zero, then(prenominal) the fuel efficiency would be equal to 3.6891 on average. If the weight increase by one then the fuel efficiency will increase by 0.0072 on average. It is also ostensible from graph 3, that the lighter the car the more fuel economical the car will...If you want to collar a full essay, drift it on our website: OrderCustomPaper.com
