We have given n = 13 , p = 0.30
And we have asked to find the probability that NO cars need new gas tanks.
That means no car has defective gas tanks. That is x=0
That is we have asked to find the probability x=0

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 = ______...

A car manufacturer has determined it takes an average time of 58 minutes to produce a car. The population standard deviation is assumed to be 7 minutes. The company pays a bonus to the workers for every car produced in 49 minutes or less. Assuming that the production time is normally distributed, answer the following questions. Let X = production time of a randomly selected car. (Round all probabilities to four decimals and times to two decimals) a) What is...

An automobile manufacturer claims that a new Hybrid model will average at least 60 miles per gallon of gas. A sample of 40 cars and and a 5% level of significance will be used for this analysis, The population standard deviation is assumed to be 7 miles per gallon. What is the Probability of a Type II error if the "true" mean is 57 miles per gallon? What is the probability of making a Type I error?

A car manufacturer has determined it takes an average time of 53 minutes to produce a car. The population standard deviation is assumed to be 7 minutes. The company pays a bonus to the workers for every car produced in 45 minutes or less. Assuming that the production time is normally distributed, answer the following questions. Let X = production time of a randomly selected car. (Round probabilities to four decimals and times to two decimals.) a) What is the...

A car manufacturer has determined it takes an average time of 51 minutes to produce a car. The population standard deviation is assumed to be 7 minutes. The company pays a bonus to the workers for every car produced in 43 minutes or less. Assuming that the production time is normally distributed, answer the following questions. Let X- production time of a randomly selected car. (Round probabilities to four decimals and times to two decimals.) a) What is the probability...

13. (11pt) Automobile manufacturers are very interested in improving the average gas mileage of their newer vehicles. One manufacturer knows that for their hybrid model car, the gas mileages are normally distributed with a mean of 32 mpg. The new model of this car is about to ship out, so the manufacturer randomly selects a sample of 7 new hybrid cars and determines that the mean gas mileage is 29.5 mpg with a standard deviation of 1.32 mpg. Is there...

The manufacturer of a new car claims that miles per gallon for the gas consumption is normally distributed with a mean of 25.9 mpg and a standard deviation of 3.1 mpg. a.) If one car is tested, what is the probability that the mean mpg is less than 24 mpg? b.) If 30 cars are tested, what is the probability that the mean mpg is less than 24 mpg? c.) If one car is tested, what is the probability that...

A bag manufacturer invested in a new production machine to improve its manufacturing productivity. 60% of all bags are produced by the new machine and the remaining bags by the old machine. The defect rates of the bags obtained from quality tests yields the following results Number of products tested New machine: 150 Old machine: 200 Number of defects: New machine: 30 Old machine: 60 If a quality control staff of the manufacturer selects a bag at random, what is...

A certain model of automobile has its gas mileage (in miles per gallon, or mpg) normally distributed, with a mean of 26 mpg and a standard deviation of 4 mpg. Find the probability that a car selected at random has the following gas mileages. (Round your answers to four decimal places.) (a) less than 20 mpg (b) greater than 28 mpg (c) between 24 and 28 mpg
