Answer #1

Increasing the significance level (alpha) also increases the statistical power.

by keeping all things constant, if the value of increases,the power of the test also increases.Because a larger α indicates a larger rejection region for the test and hence a greater probability of rejecting the null hypothesis. which results to a more powerful test.

in other words, we can say that the power of the test is reduced when we reduce the significance level.

Several factors influence statistical power for a one-sample t test. How does statistical power change (increase or decrease) for each of the following changes? When d (effect size) increases. When N (sample size) increases. When the alpha level is made smaller. Explain your answer. For example, if we know ahead of time that the effect size d is very small, what does this tell us about the N we will need in order to have adequate statistical power? (We assume...

A researcher conducts a single-sample t test and finds statistical significance at the 0.01 level. The effect size is then calculated and found to be 0.50. What might you conclude about the findings? A. These findings are exciting because statistical significance was found with a very small effect, indicating that the results are real and the chance of a Type I error are low. B. While the results of the test are statistically significant, the effect size indicates that they...

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...

What effect does increasing the confidence level have on a confidence interval? I know that increasing the confidence level increases the error bound, making the confidence interval wider. Decreasing the confidence level decreases the error bound, making the confidence interval narrower, but why?
