High airline occupancy is essential to profitability. Suppose a scheduled flight must average at least 60% occupancy to be profitable, and an examination of occupancy rate for 120 10 a.m flights from Atlanta to Dallas showed a mean occupancy per flight of 58% with SD of 11%.

Ifmis mean occupancy per flight and if the co. wishes to determine whether or not this scheduled flight is profitable, give the null hypothesis for this test.

a. m=0.6

b. m=0.6

c. m>0.6

d. m<0.6
