A business travel magazine wants to classify airports on a variety of service variables on a 0-10 scale.  A score of 0 is the lowest mark and a score of 10 the highest mark.  Airports that receive a score of 7 or higher 'might be' designated superior airports.  The magazine staff surveyed a sample of 60 business travelers at each airport to obtain ratings data.  The sample for London's Heathrow airport provided a sample mean rating of x-bar = 7.25 and a sample standard deviation of 1.052.  The null hypothesis would be U < = 7, and the alternative U > 7.   What is the P-value associated with this test?...and the proper conclusion?

P = 37.32%, accept the alternative hypothesis

P = 8.97%, Heathrow is a good facility but needs more work in the service departmen9

P = 3.54%, Heathrow is a superior facility

Heathrow is a candy bar, it's P-value is 25%.  I buy them sometimes, but I prefer M & M's

P = 1.54%, Heathrow failed all inspections
