A sample of 12 radon detectors of a certain type was selected, and each was exposed to 100 pCi/L of radon (1 pCi is one trillionth of a Curie). The resulting readings were as follows: 105.6 90.9 91.2 96.9 96.5 91.3. 100.1 105 99.6 107.7 103.3 92.4 Does this data suggest that the population mean reading under these conditions differs from 100? State and test the appropriate hypotheses using alpha = 0.05. Question 4 Determine the critical value/s. Choose the best answer. O lalpha = 0.025. df - 11) = 2.201 O talpha - 0.025, df = 11) = + 2.201 O t lalpha = 0.05, df - 11) = : 2.201 O lalpha = 0.05, df - 12) = + 2.201 O lalpha = 0.05, df - 11) - - 2.201
