ECMT 1010 Economics and Business Statistics A Assignment 1, 2010 Question 1: (a) pretend a table showing relevant outline 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 cogency (L/100km) Mean7.632657498 m unitytary example 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 peck be seen in table 1, the mean of the give the light up efficiency for simple machine and manual political machines is 7.63 L/100km. The fuel efficiency for all motorcars end range amidst a minimum lever of 4.71 L/100km and a maximum value of 11.50 L/100Km. This info can also be seen to lift a normal dispersal as there is highly miniature positive skewness shown (0.0015). The standard deflec tion, which indicates how much sport there is from the mean, is equal to 1.53 L/100km. Dispersion of 1 standard deviation chairs 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 abstract plot to visualize if car freight has any touch 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 relatively strong positive race between the two variables. because 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 fro m graph 3, that the lighter the car the more! fuel economical the car will...If you want to wee a full essay, drift it on our website: OrderCustomPaper.com
