Identify the null hypothesis, alternative hypothesis, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Test the claim about the population mean u at the level of significance a. Assume the population is normally distributed. Claim:us 45; a = 0.01; 0 = 4.3 Sample statistics: x = 46.8, n = 40 Fail to reject Ho. There is enough evidence at the 1% level of significance to support the claim. Reject Ho.

of the following statements, two are true and three are false. Which ones are true? A very small p-value is indicative of very strong evidence against the null hypothesis. A very large p-value is indicative of very strong evidence against the null hypothesis. If a null hypotheis is rejected at the 5% significance level, it would also be rejected at the 10% significance level. A very large p-value is indicative of very strong evidence against the alternative hypothesis. A very...

1.) Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim. A researcher claims that 62% of voters favor gun control. Assuming that a hypothesis test to reject this claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms. Group of answer choices There is not sufficient evidence to support the claim that 62% of voters favor gun control. There is not sufficient evidence to...

For each of the following possible conclusions, state whether the p-value would have to be less than or greater than 0.05 for you to reach that conclusion. For example, on part a. if you decide to reject the null hypothesis, does that mean your p-value is less than .05 or greater than .05? a. You decide to reject the null hypothesis b. You decide to reject the alternative hypothesis c. You accept the null hypothesis d. You accept the alternative...
