A  simple random sample of size n = 200 drivers with a valid driver's license is asked if they drive an American-made automobile. Of the 200 drivers surveyed, 118 responded that they drive an American-made automobile. Determine if a majority of those with a valid driver's license drive an American-made automobile at the a = 0.05 level of significance. .....                                                                                                                                          What type of variable is "drive an American-made automobile, or not"?                                                                      A.

A one-tailed sign test is used to test whether there is a positive difference between two populations at the 0.10 level of significance. There were nine plus signs and five minus signs. What is the correct null hypothesis? Multiple Choice Ho: rs 0.5 Ho:= 0.5 Ho:zz 0.5 Họ: H= 0.5 27 of 50 Next >

A criminologist was interested in whether there was any disparity in sentencing. She selected at random of 24 drug convictions for cocaine distribution and compared the prison terms given by two judges as below.  Judge1 Judge2 7 5 7 6 6 4 5 5 2 5 5 5 7 4 6 6 5 5 7 5 10 4 7 5 From performing a hypothesis test to determine if judge1 differs from judge2 in the mean of sentence years, what is the p-value? (Round off to three decimal places if necessary)

A p-value smaller than the significance level, a means.... We should reject the Null Hypothesis O We should not reject the Null Hypothesis
