Type I error is "rejecting the null hypothesis when it is true." If a hypothesis, whether null or alternative, specifies just a single value for the population parameter, the hypothesis is said to be composite. III.

Failing to reject an invalid null hypothesis (continuing to incorrectly assume a null is valid) is called: the beta-risk. the level of confidence. the level of significance. the power of the test. the alpha-risk.

Which of the following is true regarding standard tests of hypothesis? O The probability of committing a Type I error and a Type II error are always equal. The probability of committing a Type I error is always higher than the probability of committing a Type II error. The probabilities of committing a Type I error and Type Il error both decrease as the sample size increases. The probability of committing a Type Il error is always higher than the probability of committing a Type I error.

Suppose a chef claims that her meatball weight is less than 3 ounces, on average. Several of her customers do not believe her, so the chef decides to do a hypothesis test, at a 10% significance level, to persuade them. She cooks 15 meatballs. The mean weight of the sample meatballs is 3.1 ounces. The chef knows from experience that the standard deviation for her meatball weight is 0.6 ounces.
