Week4IndividualWorksheet.doc1.  The Willow Run Outlet Mall has two Haggar Outlet Stores, one located on Peach Street and the other on Plum Street.

A sample of ten customers at the Peach Street store revealed they spent the following ad: $17.58, $19.73, $12.61, $17.79, $16.22, $15.82, $15.40, $15.86, $11.82, $15.85. A sample of fourteen customers at the Plum Street store revealed they spent the following amounts more than they planned when they entered the store: $18.19, $20.22, $17.38, $17.96, $23.92, $15.87, $16.47, $15.96, $16.79, $16.74, $21.40, $20.57, $19.79, $14.83.

independent means.
Ho = µ1-µ2 = 0 , Ho = µ1-µ2 ≠ 0
Ho = µ1-µ2 ≥ 0 , Ho = µ1-µ2 > 0
Ho = µ1-µ2 ≤ 0 , Ho = µ1-µ2 < 0
The t-test for independence means requires that there is no cover between the two gather...
