In a test of the hypothesis H0: μ=48 versus Ha: μ>48, a sample of n =100observations possessed mean X̄ =47.4 and standard deviation s=4.6. The p-value for this test is .902 Interpret the result. Select the correct choice below and fill in the answer box to complete your choice.(Round to three decimal places as needed.) A) The probability (assuming that Ha is true) of observing a value of the test statistic that is at most as contradictory to the null...

(6 points) For each problem, select the best response. (a) In testing hypotheses, which of the following would be strong evidence against the null hypothesis? A. Obtaining data with a large P-value. B. Using a small level of significance. C. Using a large level of significance. D. Obtaining data with a small P-value. (b) In formulating hypotheses for a statistical test of significance, the null hypothesis is often A. a statement of "no effect" or "no difference". B. the probability...

A research article gives a p-value of.001 in the analysis section. Which definition of a p-value is the most accurate? The probability that the observed outcome will occur again. O The probability of observing an outcome as extreme or more extreme tharn the one observed if the null hypothesis is true. OThe value that an observed outcome must reach in order to be considered significant under the null hypothesis. The probability that the null hypothesis is true.

Suppose a random sample of 100 observations from a binomial population gives a value of p = 0.45 and you wish to test the null hypothesis that the population parameter p is equal to 0.40 against the alternative hypothesis that p is greater than 0.40. Complete parts a through c. a. Noting that p = 0.45, what does your intuition tell you? Does the value of p appear to contradict the null hypothesis? O A. Yes, because p satisfies Hg:p>0.40...

Which of the following statements regarding p-value is FALSE? Group of answer choices A. It is the probability of the observed test statistic or one more extreme, assuming the null is true. B. The smaller the p-value, the less likely that the observed difference was due to random chance. C. p-values do not indicate the magnitude or importance of the observed difference. D. Big p-values provide strong evidence against the Null hypothesis.
