For the given scenario, determine the type of error that was made, If any. (Hint: Begin by determining the null and alternative hypotheses.) Economists considered \( \$ 3.110 \) as the mean price for gallon of unleaded gasoline in the United States in a certain year. One consumer claims that the mean price for gallon of unleaded gasoline in the United States in a certain year Is less than \( \$ 3.110 \). The consumer conducts a hypothesis test and rejects the null hypothesis. Assume that in reality, the mean price for gallon of unleaded gasoline in the United States in a certain year is \( \$ 3.110 \). Was an error made? If so, what type? Answer 2 Points Prev O Yes; Type I error O No; correct decision

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 439 gram setting. Is there sufficient evidence at the 0.05 level that the bags are underfilled? Assume the population is normally distributed. State the null and alternative hypotheses for the above scehario.

A carpenter is making doors that are 2058 millimeters tall. If the doors are too long they must be trimmed, and if they are too short they cannot be used. A sample of 11 doors is taken, and it is found that they have a mean of 2070 millimeters with a variance of 400 . Assume the population is normally distributed. is there evidence at the 0.05 level that the doors are too long and need to be trimmed? Step 2 of 6: Find the value of the test statistic. Round your answer to three decimal places.
