10:25 AM Fri May 22 @ 83% TO O + 5 . True or False (2 pt. each) T F a. Increasing the level of confidence, produces a wider confidence interval T F b. For a fixed confidence level, when the sample size decreases, the margin of error of the confidence interval doesn't change. F C . The alternative hypothesis, H1, is assumed to be true at the start of any hypothesis testing problem. T F d. If the null hypothesis is true, then it will never be rejected. T F e. The power of the test for Ho will be larger as our sample size increases (fixed a). T F f. a and B are inversely related for fixed sample size. F g. If we reject Ho, then we say that Ho must be false. T F h . If we use a large enough sample size from any population, then the shape of the sampling distribution of the median would be expected to look bell-shaped. T Fi If we take a large random sample from a normal distribution, the mean of the sample will be approximately equal to the median. I F j. If we fail to reject Ho at a = .05, the probability is 0.95 that Ho is correct. 00 1 07 V
