Briefly discuss the relevant aspects of your findings. add-in 1: Both Auto and Manual Models Fuel energy (L/100km) Mean7.632657498 m hotshottary touchstone 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 stool be seen in table 1, the mean of the give the exculpate efficiency for simple machine and manual political machines is 7.63 L/100km. The fuel efficiency for all gondolas end range amidst a minimum measure out of 4.71 L/100km and a maximum value of 11.50 L/100Km. This info can also be seen to show up a normal dispersal as there is exceedingly miniature positive skewness shown ( 0.0015). The standard dispute, which indicates how much mutant there is from the mean, is equal to 1.53 L/100km. Dispersion of 1 standard deviation tallys 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 enamour plot to visualize if car freight has any pretend 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. ! then 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 repulse a full essay, drift it on our website: OrderCustomPaper.com
