You are watching: Explain why goodness-of-fit tests are always right-tailed tests.

If we perform not refuse the null hypothesis when the statement in the alternative hypothesis is true, we have actually made a Type _______ error.

TYPE IIA Type I error occurs if the null hypothesis is rejected when, in fact, the null hypothesis is true. A Type II error occurs if the null hypothesis is not rejected when, in fact, the different hypothesis is true.

If a hypothesis is tested at the = 0.05 level of meaning, what is the probability of making a kind I error?

falseAlthough sample data is offered to test the null hypothesis, it cannot be declared with 100% certainty that the null hypothesis is true. It can just be figured out whether the sample data supports or does not assistance the null hypothesis.

The tail of a test is based on the authorize of the alternative hypothesis.For a left tailed test, the authorize of the alternative hypothesis is much less than For a right-tailed test, the sign of the different hypothesis is better than For a two-tailed test, the sign of the alternative hypothesis is not equal to

The _______ represents the expected propercentage of intervals that will contain the parameter if a big number of various samples of size n is obtained. It is denoted _____

at least at 80% of intended frequencies higher than or amounts to 5;all supposed frequencies better than or equals1

TheTh chi-square goodness-of-fit tests are constantly ideal tailed bereason the numerator in the test statistic is squared, making eexceptionally test statistic, various other than a perfect fit, positive.

If the expected count of a category is much less than 1, what deserve to be done to the categories so that a goodness-of-fit test can still be performed?

The null hypothesis is rejected when the P-value is small. When the P-worth is huge, the null hypothesis is not rejected.
