Solved Question 1 The Fuel Consumption Of A New Model Of Car Chegg Question 1 the fuel consumption of a new model of car manufactured by kantanka automobile limited is being tested. in one trial, 50 cars chosen at random, were driven under identical conditions and the distance, x km on 1 liter of petrol were recorded. A random sample of n = 16 mid sized cars tested for fuel consumption gave a mean of 1 = 28.30 miles per gallon with a standard deviation of σ = 2.65 miles per gallon.
Solved The Fuel Consumption On A New Model Of Car Is Being Chegg A car manufacturer states that the fuel consumption of their new model is 5.2 litres per 100km. a sample of 36 cars was tested and the average fuel consumption of the cars was found to be 5.6 litres per 100km. the standard deviation of the sample was 2.11 litres per 100km. The eight cars had a mean fuel consumption of 6.8 l 100k with a standard deviation of 0.32 l 100k. an older model of this car had a mean fuel consumption of 7.0 l 100k, and the manufacturer wishes to test whether the true mean fuel consumption of this new model differs from 7.0 l 100k. Construct a hypothesis test to compare the average fuel efficiency of the two car models using critical value approach with a significance level of $10 \%$. [6 marks] ii. calculate the $p$ value at a $10 \%$ critical level. provide your conclusion about the difference in the mean fuel efficiency of the two car models. [4 marks] · · · copy link. Cheung wishes to model the fuel consumption of a car. he tries the quadratic model y = a (v b)^2 c where y is the fuel needed in litres per 100km and vis the speed in kmh. travelling as a passenger, he notices that the minimum fuel consumption displayed on the dashboard is 10 litres per 100km and occurs at 80kmh. (i).

(i). The mean fuel consumption will be observed and a hypothesis test will be conducted to check whether the fuel consumption is equal for both or not. since the two models are different, the sample is independent. A car manufacturer is introducing a new model, and they claim that the average fuel consumption for this model is 35 miles or more per gallon on the open road. the competitors believe this estimate is too high. you are employed by a testing agency to run a statistical test and verify the car manufacturer's claim. Question: the fuel consumption of a new model of car is being tested. in one trial, 50 cars chosen at random, were driven under identical conditions and the distances, x km, covered on 1 litre of gasoline were recorded. The fuel consumption on a new model of car is being tested. it is known that the population standard deviation is 1.5km. in one trial, 50 cars were chosen at random and driven under identical conditions. the average distance covered using 1 litre of petrol of these cars was found to be 10.5km.
