A publisher reports that 46% of their readers own a Jaguar. A marketing executive wants to test the claim that the percentage is actually more than the reported percentage.  A random sample of 220 readers found that 50% of the readers owned a Jaguar.  Is there sufficient evidence at the 0.05 level of significance to support the executive’s claim?                                    H0:  p =  0.46                                    Ha:  p  >> 0.46   What is the correct decision for this test?  What is your  conclusion, in context?  Explain your reasoning.
