We usually compare the calculated p value with 0.05. What does 0.05 mean? Why can we reject the null hypothesis if the calculated p values is smaller than 0.05?
solution:
0.05 is this significant level whether we decide reject or not null hypothesis
= 0.05
when P-value <
Reject the null hypothesis .
when P-value >
do not Reject the null hypothesis .

b-2. Find the p-value. 0.01 s p-value< 0.025 0.025 p-value < 0.05 0.05 s p-value < 0.10 p-value 010 p-value O.01 b-3. At the 0.10 significance level, What is the conclusion? Reject Ho since the p-value is greater than significance level. Reject Ho since the p-value is smaller than significance level. Do not reject Ho since the p-value is greater than significance level. Do not reject Ho since the p-value is smaller than significance level. b-4. Interpret the results at...
A one-sample z-test for a population mean is performed. Suppose that the P-value for the test is 0.04. For what significance levels (values of a) can the null hypothesis be rejected? For a = 0.04 For all values of a greater than or equal to 0.04 For a = 0.05, 0.10 For all values of a smaller than 0.04
If your level of statistical significance (alpha) is 0.05, and the p-value calculated from your data is p = 0.04, you reject the null hypothesis. (state your decision rule) A. True B. False

Can someone explain why this answer is A rather than D? I am
very confused
15. Suppose the P-value for testing hypotheses was computed to be 0.057. Which of the following statements is correct? e we can reject the null hypothesis at a = 0.10 but not at 0.05 or 0.01 b) we can reject the alternative hypothesis at a = 0.01 and 0.05 but not at 0.10 c) we can reject the alternative hypothesis at a = 0.05 and...
1A. With a significance level of 0.05, you observe a p-value of 0.09. What conclusion should you draw? a. Reject the null hypothesis b. Accept the null hypothesis c. Fail to reject the null hypothesis d. Fail to accept the null hypothesis 1B. With a significance level of 0.05, and a p-value of 0.02, what conclusion should you draw? a. Reject the null hypothesis b. Accept the null hypothesis c. Fail to reject the null hypothesis d. Accept the alternative...
(c)What is the test statistic? Give your answer to 3 decimal places. 5.971 (d)The p-value = 0.005. Which of the following is an appropriate conclusion? The data provides very strong statistical evidence that the average SENS reading after antihypertensive treatment is lower than the average SENS reading before antihypertensive treatment. The data does not provide statistical evidence that the the average SENS reading after antihypertensive treatment is lower than the average SENS reading before antihypertensive treatment. The data provides very...
A hypothesis test is performed at the α = 0.05 level of significance. The p-value is determined to be 0.03. Therefore, we know that we would _______________. either reject or fail to reject the null hypothesis, depending on the value of the test statistic. reject the null hypothesis know that a 99% confidence interval would contain the value specified in the null hypothesis. fail to reject the null hypothesis
IPS 19 When testing for independence, what decision/conclusion can we make when the P-value is 0.03 and the significance level is 0.05? Enough evidence to conclude that the two variables are independent Reject the alternative hypothesis Enough evidence to conclude that the two variables are dependent Reject the null hypothesis
If we find a p-value between 0.30 and 0.40, then do we reject or retain the null hypothesis at the 5% significance level? Retain the null hypothesis Reject the null hypothesis Question 23 1 pts We want to compare cholesterol levels between men and women, so we collect a sample of 20 women and 30 men. The group of men in our sample have a mean of 240.0 with standard deviation 35.0, and the women have a mean of 210.0...
