It is known that the status quo of the population mean is 88. A sample of size 50 is taken and the sample mean is computed as 85. You decided to reject the null hypothesis that the population mean is at least 88 and to be in favor of the alternative hypothesis that the population mean is less than 88.

Select one:

A. We may commit a Type II error if the null hypothesis is false.

B. We may commit a Type I error if the null hypothesis is true.

C. We may commit a Type II error if the null hypothesis is true.

D. We may commit a Type I error if the null hypothesis is false.

A sample of size 12, taken from a normally distributed population has a sample mean of 85.56 and a sample standard deviation of 9.70. Suppose that we have adopted the null hypothesis that the actual population mean is equal to 89, that is, H0 is that μ = 89 and we want to test the alternative hypothesis, H1, that μ ≠ 89, with level of significance α = 0.1. a) What type of test would be appropriate in this situation?...

1. Insofar as we must generalize from a sample to a population, the observed difference between the sample mean and the hypothesized population mean a) can't be interpreted at face value. b) might be due to variability or chance. c) might be real. d) is described by all of the above 2. The advantage of a one-tailed test is that it increases the likelihood of detecting a a) false null hypothesis. b) false null hypothesis in the direction of concern....

We have a left tail one sample test for the population mean. Assume the null hypothesis is true. Use 4% for the significance level. The sample size is 27, the sample mean is 32.8, the sample standard deviation is 4.1, and the null mean is 35. The test result is (a) a correct decision (b) a Type I error (c) a Type II error 3. The test statistic value for the previous problem is
