For the following, Calculate the Probability and Type II errors. Assume an level of significance of α= 0.05 .

•Q1: For testing Ha: u < 62, true population standard deviation= 15, sample size = 64, and we miraculously know that our true population mean is really 60. What is the type II error? Power? Also is our Power up to par (at least 0.8).

•Q2: For testing Ha: u >65, true population standard deviation = 12, sample size = 36, and we miraculously know that our true population mean = 66. What is the type II error? Power? Also is our Power up to par (at least 0.8).

•Q3: For testing Ha: u ≠ 65, true population standard deviation = 12, sample size = 64, and we miraculously know that our true population mean= 65. What is our power? Type II error? Is our power up to par (at least 0.8).

•Helpful Tip: You can also use the youtube videos, labeled mentioned on the previous slide, for help.

Please help me with the Q1,2,3

Type I and II Errors

A manufacturer of 40-amp fuses wants to make sure that the mean amperage at which its fuses burn out is in fact 40. If the mean amperage is lower than 40, customerswill complain because the fuses require replacement too often. If higher, the manufacturer might be liable for damage. To verify the amperage of the fuses, a sample offuses is to be selected and inspected. If a hypothesis test were to be performed on the resulting data, what null and...

8) Errors: Type I and Type II are errors that are possible even when a hypothesis test is done correctly. A hypothesis test is based on probabilities (p-values) This means there is always a probability of drawing the wrong conclusion even when done correctly. Please review the following: a.) What are type I and type II errors? b.) Be able to discuss what a type I or type II error is in a given scenario c.) What is the relationship...
