Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, student T distribution, or neither.

Claim: u=101. Sample data: n=11 x=108, s=15.4. The sample data appears to come from a normally distributed population with unknown u and o.

"A test to determine whether a certain antibody is present is 99.6% effective. This means that the test will accurately come back negative if the antibody is not present (in the test subject) 99.6% of the time. The probability of a test coming back positive when the antibody is not present (a false positive) is 0.004. Suppose the test is given to five randomly selected people who do not have the antibody. (a) What is the probability that the test...

CHAPTER 10: INTRODUCTION TO HYPOTHESIS TESTING: The z Test Key Terms Sampling distribution of z --- the distribution of z values that would be obtained if a value of z was calculated for each sample mean for all possible random samples of a given size from some population. Z Test for a population mean --- A hypothesis test that evaluates how far the observed sample mean deviates, in standard error term units, from the hypothesized population mean. Null hypothesis (Ho)...
