if you have a mean of 24.8 mpg and a SD of 6.2 mpg if you use a normal model what is the probability that a random selected RV is going to avg:

< 23 mpg

> 17 mpg

20-25 (between) mpg

the Environmental Protection Agency measures a mean gas mileage for recently tested cars as 24.8 mpg with a standard deviation of 6.2 mpg. The dataset on Fuel economy in StatCrunch gives an average of 24.2 mpg with a standard deviation of 6.5 mpg. Joe’s car is estimated at 30 mpg. (a)   Calculate the z-scores to find the relative tab at both sources (the Exercise and the Dataset). (b)   Relative to the other cars, with which source will Joe have the...

The Environmental Protection Agency (EPA) fuel economy estimates for automobile models tested recently predicted a mean of 24.8 mpg and a standard deviation of 6.2 mpg for highway driving. Assume that a Normal model can be applied. a) Draw the model for auto fuel economy. Clearly label it, showing what the 68-95-97 Rule predicts. Use StatCrunch, Excel, or Minitab. b) In what interval would you expect the central 68% of autos to be found? c) About what percent of autos...

Test the claim that the mean gas MPG (city) is equal for all three car sizes. This requires the use of one-way ANOVA (single factor) to test for equality of three or more means (12.2). Calculate the null and alternate hypothesis, test statistic, critical value, p-value, and state the conclusion. Size Class Gas MPG - City Driving Small 25 Small 27 Small 25 Small 25 Small 29 Midsize 19 Small 22 Midsize 20 Midsize 21 Midsize 21 Small 20 Midsize...

Q1. IQ scores are normally distributed with a population mean of 100 and SD 15. If you select a sample of 25 individuals how high would the sample mean have to be to say that probability of getting a sample mean that high or higher is 0.05? Round your answer to whole number. Q2. 10% of the items produced by a machine are defective. A random sample of 100 items is selected and checked for defects. What is the probability...

A researcher proposes to model daily coffee consumption among college students by a normal distribution with mean 20 oz and a standard deviation 4 oz. What is the probability that a randomly selected student will have coffee consumption in the range [mean-SD, mean+SD]? 2. Verify your answer by using R. Generate 1 million random samples from the normal distribution with appropriate mean and SD. Does the normal distribution is in between[ 20-4, 20+4]?? For the R code will that be...

Two models of a popular pick-up truck are tested for miles per gallon (mpg) gasoline consumption. The Pacer model was tested using a random sample of n1=9 trucks and the sample mean of 27.3 mpg with sample standard deviation s1=6.2 mpg. The Road Runner model was tested using a random sample of n2=14 trucks. The sample mean was 22.5 mpg with sample standard deviation s2=6.8 mpg. Does this indicate that the population mean gasoline consumption for the Pacer is higher...
