Questions 14-19: The proposed federal health standard for the maximum acceptable level of exposure to microwave radiation is an average of 26 W/cm2. It is suspected that a radar installation used for air traffic control may be pushing the average level of radiation above the safe limit. A random sample of 9 measurements is taken. The sample mean is 32.93 and sample standard deviation is 9. Assume normality of the data. 14. What are the appropriate Ho and HA? O Ho : / = Ho and HA : # # #o with Ho = 26 O Ho : H = Ho and HA : # # Ho with Ho = 32.93 O Ho : H = Ho and HA : / > Ho with Mo = 32.93 O Ho : H = Ho and HA : H > Ho with Ho = 26 15. What is the value of the test statistic? O -0.89 O 2.9 O 2.31 O 1.86 O -1.4 16. What is your conclusion using o = 0.222? O Fail to reject Ho O Accept Ho O Reject Ho O Reject HA O Fail to reject HA 17. What is the p-value? O 0.025 O 0.118 O 0.158 O 0.172 O 0.048 18. What is your conclusion using o = 0.015? O Accept Ho O Reject Ho O Reject HA O Fail to reject HA O Fail to reject Ho
