  2. Parts a, b, c CANNOT be answered. The probability of a Type I error depends on the significance level. The probability of a Type II error depends upon the confidence level. You have provided neither...

  3. First off, VARx > 43.12 implies you'd reject if the variance of the sample is greater than 43.12. this is a very bad idea since you are looking at the mean. So if VARx is the mean we should use a less confusing notation, such...

  4. The probability of a Type I error is bounded by the significance level of the test. You did not define a significance level or a rejection region here. there is not enough information given to find the probability of a Type I Error...
