Given a specified level of significance the absolute value of the critical value will be smaller for a one-tailed test than for a two-tailed test.Suppose that the weight of cereal in a box is normally distributed around a mean of 20, measured in ounces, with a standard deviation of 0.14. What is the z value for a box with 20.07 ounces of cereal? Answer to three decimal places if needed.
A Type I error is when we fail to reject the null hypothesis even though it is false.
True or False?
The p-value is
|
1 minus the power of a test.
|
|
the exact or observed level of significance.
|
|
the probability of a Type II error.
|
|
the same as the critical value.
