can be used to determine whether a statement about the value of a population parameter should or should not be rejected.

Care must be taken to structure the hypotheses appropriately so that the -------provides the information the researcher wants.
Many applications of -------involve an attempt to gather evidence in support of a research hypothesis.
In such cases, it is often best to begin with the ------- and make it the conclusion that the researcher hopes to support.
The conclusion that the research hypothesis is true is made if the sample data provide sufficient evidence to show that the
A new teaching method is developed that is believed to be better than the current method.Alternative Hypothesis:
A new teaching method is developed that is believed to be better than the current method.Null Hypothesis:
A new drug is developed with the goal of lowering blood pressure more than the existing drug.Alternative Hypothesis:
A new drug is developed with the goal of lowering blood pressure more than the existing drug.Null Hypothesis:
Null Hypothesis as an Assumption to be ChallengedWe might begin with a ---------thata statement about the value of a populationparameter is true.We then using a --------to challenge the assumption and determine if there is statistical evidence to conclude that the assumption is incorrect.In these situations, it is helpful to develop the -------
The probability of making a Type I error when the null hypothesis is true as an equality is called the
------ is the probability, computed using the test statistic, that measures the support (or lack of support) provided by the sample for the null hypothesis.
If the ----- is less than or equal to the --------, the value of the test statistic is in the ------.
We can use the -------to find the z-value with an area of alpha in the lower (or upper) tail of the distribution.

Confidence Interval Approach to Two-Tailed Tests About a Population MeanSelect a simple random sample from the population and use the value of the sample mean to develop the ------for the population mean
If the confidence interval contains the hypothesized value u0, ------ Otherwise, reject H0. (Actually, H0 should be rejected if u0 happens to be equal to one of the end points of the confidence interval.)
The format of the t distribution table provided in most statistics textbooks does not have sufficient detail to determine the--------for a hypothesis test.
