A car manufacturer claims that their latest model offers an average mileage of 30 miles per gallon. You conducted a test by driving the car for a week and recorded the mileage for 40 different trips. The mean mileage was found to be 28.5 miles per gallon with a standard deviation of 3 miles per gallon. Conduct a hypothesis test to determine whether the manufacturer's claim is valid. describe it in detail.

A car manufacturer advertises that their new model of car gets an average of 32 miles per gallon. A consumer group tests 64 of these cars and finds that they get an average of 30 miles per gallon with a standard deviation of 4 miles per gallon. Use a 1% level of significance to test the manufacturer's claim. Assume a normal distribution.

A car manufacturer claims that their new hybrid model can achieve an average of 50 miles per gallon (mpg) on the highway. A consumer advocacy group tests 30 vehicles of this model and finds that their average highway mileage is 48 mpg, with a standard deviation of 2.5 mpg. Conduct a hypothesis test at a 1% significance level to determine if the manufacturer's claim is valid.

A car manufacturer claims that their latest model can go at least 30 miles per gallon. A consumer protection agency, skeptical of the claim, randomly selects 50 of these cars for testing. The sample average miles per gallon is 28.5 with a standard deviation of 4 miles. Test the manufacturer's claim at the 0.01 significance level.
