We would like to test whether the population mean is less than 30. Suppose that a hypothesis test is conducted to determine if the mean of the population has decreased. Describe what a Type II error would mean for this example.

A hypothesis test is completed and we have sufficient evidence that a certain population mean is more than 215. Suppose that in reality the population mean is more than 215. Determine if a correct decision has been made. If an error has been made, indicate which type of error it is.

In the context of the level of significance, when does a Type II error occur?Multiple choice question.When the group means are equalWhen the group means are unequalWhen a true hypothesis is rejectedWhen a false hypothesis is accepted

35.In one tail test for the population mean if the null hypothesis is not rejected when the alternative hypothesis is true then which of the following happens?  A. Type 2 error  B. Type 1 error  C. No error  D. Two tailed test should've been used

An agriculture company is testing a new product that is designed to make plants grow taller. This can be thought of as a hypothesis test with the following hypotheses.H0: The product does not change the height of the plant.Ha: The product makes the plant grow taller.Is the following an example of a type I or type II error?The sample suggests that the product does not change the height of the plant, but it actually does make the plant grow taller.Group of answer choicesType IIType I

In statistics, a Type I error is called a false positive. They occur when we mistakenly reject a hypothesis that is actually true. A Type II error is a false negative. They occur when we mistakenly accept a hypothesis that is actually false.Imagine you run an experiment to determine whether the kilometers per kilowatt(km/kWh) differs significantly between two models of electric vehicle: Tesla Model Y and Chevrolet Bolt. You hypothesize that there is no difference in their efficiency. Based on your findings, you determine your hypothesis is right and there is no difference between the km/kWh. Later, you learn that there is a significant difference in the km/kWh of these two models. What type of error did you commit?
