I am interested in knowing if people at work take longer lunches on Friday than on Mondays.

My null would be:

Ho: All workers take the same time for lunch on Friday than they do on Monday
Ha: Workers take longer lunches on Friday then Monday

Now, in this case, I think a sufficient level of significance would be 0.05. I am comfortable ...

    Justify your choice in terms of the probability of making a Type I error and the probability of making a Type II error. Hypotheses and Significance Please identify a research question that can be addressed with a hypothesis test.

  • Type I and Type II Error

    The probability of a Type I error (a) is called the significance level and is set by the experimenter.

    There is a tradeoff between Type I and Type II errors.

  • Statistics, Research and Evaluation

    Theoretically, however, we know that as the significance level decreases (Type I error), the probability a Type II error increases. 3. What does this suggest about the tradeoffs between Type 1 and Type II errors?

  • Effect of significance level on likelihood of errors

  • Hypothesis Test: Chi-Square Test of Variance

    The alternative hypothesis is that older people are not more likely to buy American cars than younger people. When discussing null hypothesis, look at Type I and Type II errors. Type I errors are also called the level of significance.

  • Type I or Type II errors?

    This probability of a type I error can be precisely computed as P(type I error) = significance level The exact probability of a type II error is generally unknown.

  • Type I and Type II Errors

    Type I and type II errors are examined in 200 clinical trials to test the effectiveness of anti-anxiety drugs.

  • Hypothesis Testing and Linear Regression Analysis

    Solution: The level of significance is the maximum probability of committing a type I error. The two errors associated with the level of significance are: Type I error and Type II error.
