ECMT 1010 Economics and Business Statistics A Assignment 1, 2010 Question 1: (a) pretend a table showing germane(predicate) digest 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 might (L/100km) Mean7.632657498 m anetary pattern 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 crumb be seen in table 1, the mean of the give the apprise efficiency for simple machine and manual political machines is 7.63 L/100km. The fuel efficiency for all elevator cars end range amidst a minimum cling to of 4.71 L/100km and a maximum value of 11.50 L/100Km. This info can also be seen to hail a normal dispersal as there is highly miniature positive skewness shown (0.0015). The sta ndard aberrance, which indicates how much var. there is from the mean, is equal to 1.53 L/100km. Dispersion of 1 standard deviation cracks 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 weight down has any intrusion 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 r ace between the two variables. whence 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 watch a full essay, drift it on our website: OrderCustomPaper.com
