We perform a statistical test to examine if the mean lifetime of lab mice increases when given vitamin B12 compared to a placebo. Which of the following is a Type I error?

Conclude that Vitamin B12 increases the mean lifetime when in fact it does.

Conclude that Vitamin B12 does not increase the mean lifetime when in fact it does not.

Conclude that Vitamin B12 increases the mean lifetime when in fact it does.

Conclude that Vitamin B12 increases the mean lifetime when in fact it does not.

Expert Solution

Type I error is probability of rejecting the true null hypothesis so in this case, it will be:

Conclude that Vitamin B12 increases the mean lifetime when in fact it does not.

Option D is correct.

Conceptually, what are we doing when we test for statistical significance (such as in a z-test or t-test)? Where does the commonly used 95% confidence level come from? What is an effect size and what additional information does it provide about a finding?

When we carry out a statistical test with significance level α = 5%, the probability of rejecting the null hypothesis when it is true is 5%. Suppose that we independently select 5 random samples of size 100, and for each sample carry out the same statistical test with significance level 5%. We know that the null hypothesis is true. What is the probability that we reject the null hypothesis at most once out of the 5 tests?

Question 1 We want to conduct a statistical test to determine how a sample mean compares to a population mean. We have alpha = 0.05. We have 40 observations in the sample, and our sample is normally distributed. We do not know our population standard deviation. Which test would we use?
