- If you use a 0.02 level of significance in (two-tail) hypothesis test, what is your decision for rejecting a null hypothesis that the population mean is 750 if you use the Z test? Which of the following decision rules is correct? A. Reject H_{0} if -2.05+2.05 . Reject H 0 if-2.33+2.33 .When conducting an ANOVA on sbp and genhelth, the p-value is 0.02. Therefore we conclude reject the null hypothesis at 1% level, mean sbp different for all categories of genhelth no evidence to reject the null hypothesis of equal means reject the null hypothesis at 5% level, mean sbp different for all categories of genhelth reject the null hypothesis at 5% level, mean sbp different for at least one category of genhelth Formula sheet.docx Ef 88 13°C A 0 4, N Type here to search ORandom samples of 100 parts from production line A had 12 parts that were defective and 100 parts from production line B had 5 that were defective.

- State true or false explain in some lines In a completely randomized 1 way ANOVA, with other things being same, the prob of rejecting the null hypothesis decreases as the sample means gets farther from/ closer to each otherdevelop a research question that can be addressed with the independent (not a dependent /paired-samples t test) making sure to state the null and alternative hypotheses (in words)The accompanying table lists survey results obtained from a random sample of different crime victims. Homicide Robbery Assault Criminal was a stranger 40 72 Crimial was an acquaintance or relative 13 64 Test at the 0.05 level the claim that the type of crime relates to whether the criminal is a stranger. The null hypothesis (H_0) is Select one: O a. p_{criminal was a stranger} = p_{crimial was an acquaintance or relative} O b. p_{homicide} = p_{robbery} = p_{assault} =1/3 O c. The type of crime is dependent on whether the criminal is a stranger O d. None of the other answers in necessary true. O e. The type of crime is independent of whether the criminal is a stranger
- Write the null and alternative hypotheses for carrying out an analysis of variance (ANOVA) on these dataDescribe a potential example of an "Analysis of Variance (ANOVA)" that could be conducted within the social sciences, and list what you believe the null and alternative hypotheses would be for this study. No data or calculations are necessary whatsoever, but you should describe why you developed your chosen hypotheses (e.g., based on your own understanding of current research, real world observations, a wild guess, etc.). In addition, specify your groups/levels, and remember that ANOVA is used to test for mean differences when there are more than two groups/levels. Thus, you should describe an example with 3 or more groups/levels.The null and alternative hypotheses for a test are given, as well as some information about the actual sample and the statistic that is computed for each randomization sample. Indicate whether the test is a left-tail test, a right-tail test, or a two-tailed test. H0:p1=p2H0:p1=p2 vs Ha:p1<p2Ha:p1<p2Sample: p1^=0.3p1^=0.3, n=20n=20, p^2=0.167p^2=0.167, n=12n=12Randomization statistic: p^1−p^2p^1-p^2 (a) Indicate where the randomization distribution will be centered. (b) Indicate whether the test is a left-tail test, a right-tail test, or a two-tailed test.
