In hypothesis testing, the test of hypothesis is developed assuming the ALTERNATIVE hypothesis is true.

	In hypothesis testing, the test of hypothesis is developed assuming the ALTERNATIVE hypothesis is true.
	In hypothesis testing, the NULL hypothesis states that a parameter of interest is equal to a specific value.
	For larger sample sizes (n>30) with the STANDARD DEVIATION KNOWN, the t-distribution should be used to test hypotheses about the population mean.
	In hypothesis testing, the ALTERNATIVE hypothesis states how the parameter of interest differs from the null hypothesis value.
	The p-value is determined by the ALTERNATIVE hypothesis.
	Type I error can be defined as the probability the null hypothesis is true.
	Type II error is the probability of failing to reject H0 when it is false.
	The SMALLER the significance level, the stronger the evidence needed to reject H0.
	The SIGNIFICANCE LEVEL determines how unusual an outcome must be in order to reject or fail to reject the null hypothesis.
	The p-value is the probability the null hypothesis is true.

In hypothesis testing, which hypothesis do we test? Experimental Research Alternative Null As part of your research, you have developed the following hypothesis to test: “there will be no association between residents’ socioeconomic status and level of education”. What type of hypothesis is this? One tailed Alternative Directional Two tailed What do we call the situation where we believe there is a genuine effect in our population when in fact there is not? Type II error Type...

in hypothesis testing if the null hypothesis is rejected -the alternative hypothesis is likely to be true - no conclusions can be drawn from the test -the data must have been accumulated incorrectly -the sample size has been to small

True or False 1) If the alternative hypothesis of an ANOVA F-test is true, we expect MSG to be less than MSE. test 2) An F distribution depends on two differrent degrees of freedom, one for numerator and the other for denominator. 3) If the conditional distributions in a two-way table are similar to each other, one can conclude that the two variables in the two-way table are associated. 4) In a two-way table, if the expected counts are about...

True or False? With testing the significance of correlation, a hypothesis test can be used to determine whether the sample correlation coefficient has enough evidence to conclude that the population correlation coefficient is significant.

Two key concepts in hypothesis testing are the null and the alternative hypothesis. Formulating the hypothesis test in the right manner, i.e. by correctly formulating null and alternative hypothesis is the first step towards solving the problems in the right manner. How do we represent these concepts tl (i.e. what abbreviation we use to denote null and alternative hypothesis)?

1) What is a hypothesis, a hypothesis test, a null hypothesis and an alternative hypothesis? 2) What is a P-value, critical value and a test statistic? Provide an example of each and describe how they are used to test claims. 3) When conducting a hypothesis test, what is the difference between the P-value method and the critical-value method? 4) List and explain all the steps for performing a hypothesis test. Directions: write the finding of these questions in a short...

In hypothesis testing, we can reject a. the null hypothesis. b. the alternative hypothesis. c. both the null and the alternative hypotheses. d. neither the null and the alternative hypotheses.

Explain how a hypothesis testing for a mean is similar to a hypothesis test for a proportion. Then explain how z-test for a mean is different than a t-test for a mean.
