A study came up with a p-value of 0.042 with a significance level of 0.05. What can you conclude about the claim; would you reject the null hypothesis or fail to reject the null hypothesis?

Homework Answers

Answer #1

Our conclusion would be to reject the null hypothesis. [ANSWER]

Explanation:

In a hypothesis test, two cases arise:

Case I: p-value < significance level (In this case we reject the null hypothesis)

Case II: p-value > significance level (In this case we do not reject the null hypothesis)

Here, since the p-value = 0.042 < 0.05 = significance level, we reject the null hypothesis.

Please define p-value. What a p-value is and how to interpret its value. Typically, a p-value of 0.05 is used as the significance level. This means that if p > 0.05 we fail to reject Ho (null hypothesis). If p < 0.05 we reject Ho. Discuss whether or not you think 0.05 is too strict or too liberal a value for making statistical claims. Please respond to at least one other student's post.

Statistical significance (alpha level; p-value) reflects the odds that a particular finding could have occurred by chance. If the p-value for a difference between two groups is 0.05, it would be expected to occur by chance just 5 times out of 100 (thus, it is likely to be a “real” difference). We define a p-value of less than 0.05 to indicate statistical significance. Suppose a pizza place claims their delivery times are 30 minutes or less on average but you...
