A sample of 12 radon detectors of a certain type wasselected, and each was exposed to 100 pCi/L of radon. Theresulting readings were as follows: 105.6 90.9 91.2 96.9 96.5 91.3100.1 105.0 99.6 107.7 103.3 92.4a. Does this data suggest that the population mean readingunder these conditions differs from 100? State and testthe appropriate hypotheses using .b. Suppose that prior to the experiment a value ofhad been assumed. How many determinations wouldthen have been appropriate to obtain for thealternative ?
