O words Question 21 8 pts A test team takes readings from the miles per gallon (mpg) estimate reading in a new car while driving at 60 mph. The sample consists of 30 readings and has a mean of 31.3 mpg and a standard deviation of 117 mpg. The average mpg of all new cars is 27.6 mpg although the standard deviation is unknown. Is there evidence the new car has superior gas mileage? Conduct a test of significance stating...

It is necessary for an automobile producer to estimate the number of miles per gallon (mpg) achieved by its cars. Suppose that the sample mean for a random sample of 40 cars is 28.8 mpg and assume the standard deviation is 2.3 mpg. Now suppose the car producer wants to test the hypothesis that μ, the mean number of miles per gallon, is 29.3 against the alternative hypothesis that it is not 29.3. Conduct a test using a significance level...

The combined gas mileage of mid-size cars varies with mean 25 miles per gallon (mpg) and a standard deviation of about 5.3 mpg. A particular rental car agency typically has 88 midsize cars in its lot. Assume the distribution of combined gas mileage of mid-size cars is Normal. Find the probability that the combined gas mileage for a randomly selected car in the lot is higher than 25 mpg. Find the probability that the mean combined gas mileage for all...

Under specified conditions, an automobile manufacturer is concerned about the miles per gallon (mpg) of its new compact car. For cars of the same class, the average is 23 with a standard deviation of 5 mpg. To investigate, the manufacturer tested 28 cars in which the average was 19 mpg. What can the car manufacturer conclude with α = 0.05? a) Compute the corresponding effect size(s) and indicate magnitude(s). If not appropriate, input and select "na" below. d = ______...

The manufacturer of a new compact car claims the miles per gallon (mpg) for the gasoline consumption is mound-shaped and symmetric with a mean of 24.6 mpg and a standard deviation of 9.5 mpg. If 30 such cars are tested, what is the probability the average mpg achieved by these 30 cars will be greater than 28?
