question 4

4) The mean credit card debt among households in one state is $8400. A 4) hypothesis test is to be performed to decide whether the mean credit card debt for households in the formerly affluent town of Rich-No-More differs from the mean credit card debt for the state. The hypotheses are H : H= $8400 H : u = $8400 where u is the mean credit card debt for all households in Rich-No-More. Explain the meaning of a correct decision. A) A correct decision would occur if, in fact, = $8400, but the results of the sampling lead to the conclusion that u = $8400; or if, in fact, H $8400 and the results of the sampling lead to that conclusion. B) A correct decision would occur if, in fact, = $8400, and the results of the sampling do not lead to rejection of that fact; or if, in fact, u z $8400 and the results of the sampling do not lead to rejection of the null hypothesis that u = $8400. C) A correct decision would occur if, in fact, u= $8400, and the results of the sampling do not lead to rejection of that fact; or if, in fact, J z $8400 and the results of the sampling lead to that conclusion. D) A correct decision would occur if, in fact, u = $8400, and the results of the sampling do not lead to rejection of the null hypothesis that H = $8400
