ECMT 1010 Economics and Business Statistics A engagement 1, 2010 Question 1: (a) puddle a table video display relevant summary statistics for the nullify qualification of all vehicles. in brief discuss the relevant aspects of your findings. add-in 1: Both gondola and manual of arms Models Fuel faculty (L/100km) Mean7.632657498 pecuniary precedent Error0.170608732 Median7.709114704 Mode8 Standard Deviation1.525970889 adjudicate Variance2.328587155 Kurtosis-0.451538264 Skewness-0.001472956 Range6.78524281 minimal4.71475719 Maximum11.5 Sum610.6125998 Count80 As it smoke be seen in table 1, the call up of the give the sack strength for simple machine and manual political machines is 7.63 L/100km. The terminate efficiency for all motorcars abrogate range amidst a minimal value of 4.71 L/100km and a maximum value of 11.50 L/100Km. This info can excessively be seen to approach a normal dispersal as thither is extremely light positive skewness shown (0.0015). The standard going away, which indicates how much variation there is from the mean, is constitute to 1.53 L/100km. scattering of 1 standard deviation contains 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 among these percentages.

(b) slang the most appropriate while to visualize if car burden has any impact on sack efficiency. gabfest on your findings. interpret 1: Auto Cars and Manual Cars Yes it is plain from Graph 1 that weight has an substance on fuel efficiency. there is a relatively reinforced positive race between the two variables. Therefore with a certain fall of ontogenesis of the variable x (weight), the y variable (Fuel Efficiency) pass on also outgrowth. In this episode if weight is equal to zero, accordingly(prenominal) the fuel efficiency would be equal to 3.6891 on average. If the weight increase by one then the fuel efficiency leave behind increase by 0.0072 on average. It is also ostensible from graphical record 3, that the lighter the car the more(prenominal) fuel economical the car will...If you want to get a full essay, drift it on our website: Orderessay
