Which one of the following statements is FALSE?

a.

The p-value gives an indication of how close our estimate is to the hypothesized value of the parameter.

b.

Assume the level of significance for a test and the effect size of interest are both fixed. Then, increasing the sample size will decrease P[Type2 error].

c.

When the null hypothesis is TRUE, P[Type 1 error] = the level of significance of the test (alpha)

d.

The p-value is a conditional probability.

e.

The p-value is the probability of getting our sample result.

Answer #1

The p-value is the probability that a result at least as extreme as that which was actually observed would occur given that the null hypothesis is true.

a) False

d) FALSE. A p-value is a conditional probability—given the null hypothesis is true, it’s the probability of getting a test statistic as extreme or more extreme than the calculated test statistic.

e) False,  The p-value is the probability that a result at least as extreme as that which was actually observed would occur given that the null hypothesis is true.

True or False 1. Hypothesis tests are robust to the significance level you choose, meaning regardless of the alpha level: .10, .05, or .01, our test will have the same conclusion or result. 2. If alpha is greater than the p-value, then we reject the null hypothesis. 3. The p-value is strictly the probability the null hypothesis being true. 4. Hypothesis tests are accessing the evidence provided by the data and deciding between two competing hypotheses about the population parameter....

Consider the following statements. (i) The smaller the p-value, the stronger the evidence is in favor of the null hypothesis. (ii) The p-value forms the borderline between values of the test statistic that would result in rejecting the null hypothesis and values of the test statistic that would result in not rejecting the null hypothesis. (iii) The p-value is calculated under the assumption that the null hypothesis is true. Determine which of the above statements are true (1) or false...
