The accompanying table shows the wait times (minutes) from six rides located in three different Walt Disney World theme parks. Wait times were reported by Disney and wait times at 10 AM and 5 PM were recorded on 50 different days (five rows are shown in the accompanying table). Use the 10 AM wait times for Space Mountain, Rock 'n' Roller Coaster, Tower of Terror, and Flight of Passage. Use a

Part 1

Determine the null hypothesis.

H0:

mu 1 equals mu 2 equals mu 3 equals mu 41=2=3=4

mu 1 greater than mu 2 greater than mu 3 greater than mu 41>2>3>4

mu 1 less than mu 2 less than mu 3 less than mu 41<2<3<4

At least one of the means is different from the othersAtleastoneofthemeansisdifferentfromtheothers

All of the means are different
