(a) What would be an acceptable p-value in performing statistical analyses following an experiment? (b) Why do we choose this p-value versus any other p-value. (c) What would the results be by raising or lowering the p-value from the one you stated above? (Would lowering or raising the p-value be more or less stringent in failing to reject the null hypothesis?)
a)
The acceptable p-value in performing statistical analyses following an experiment should be lower than 0.05. It signifies a powerful confirmation opposite to the null theory as there is lower than 5 percent anticipation that null is legitimate. Accordingly, null theory could be rebuffed and alternative theory could be acknowledged.

If, in a (two-tail) hypothesis test, the p-value is 0.1611, what is your statistical decision if you test the null hypothesis at the 0.09 level of significance? Choose the correct answer below? A. B. ° C. D. Since the p-value is less than α, do not reject Ho Since the p-value is greater than α, do not reject Ho. Since the p-value is less than α, reject Ho Since the p-value is greater than α, reject Ho
, in a (two-tail) hypothesis test, the p-value is 0.0758, what is your statistical decision if you test the null hypothesis at the 0.05 level of significance? Choose the correct answer below? Please Explain why because I am very confused with this chapter. Thanks! A. Since the p-value is less than alpha comma do not reject Upper H 0 . B. Since the p-value is less than alpha comma reject Upper H 0 . C. Since the p-value is greater...
If, in a one-tail hypothesis test, the p-value=0.5122 what is the statistical decision if the null hypothesis is tested at the 0.07 level of significance? What is the statistical decision? A) Since the p-value is less than α=0.07, do not reject H0. B) Since the p-value is greater than or equal to α=0.07, do not reject H0. C)Since the p-value is greater than or equal to α=0.07, reject H0. D) Since the p-value is less than α=0.07, reject H 0...
You perform a statistical test and obtain a P-value of 0.08. You would typically conclude that you reject your null hypothesis. True False
Explain what a P-value is. What is the criterion for rejecting the null hypothesis using the P-value approach? Explain what a P-value is. Choose the correct answer below. OA. A P-value is the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true B. A P-value is the number of standard deviations that the observed proportion is from the proportion stated in the...
Suppose a researcher is testing the hypothesis Ho: p = 0.6 versus H1:p*0.6 and she finds the P-value to be 0.29. Explain what this means. Would she reject the null hypothesis? Why? Choose the correct explanation below. O A. If the P-value for a particular test statistic is 0.29, she expects results no more extreme than the test statistic in about 29 of 100 samples if the null hypothesis is true. OB. If the P-value for a particular test statistic...
H0: P=0.6 versus H1 P>0.6 n=200, x=135, a=0.1 a) What is the P value? b) Do we reject or accept the null hypothesis?
Question 21 If the p-value of a left sided test is 0.03, what would be the decision at a 5 % level of signficance ? None of the above Reject the alternative hypothesis Reject the null hypothesis Fail to reject the null hypothesis
On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. What can you conclude? A. 2(0.21) = 0.42 < 0.5; the test is not statistically significant. B. If the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. C. 0.21 > 0.05; the test is statistically significant. D. If the null hypothesis is...
