The amount of money spent by 12 randomly selected customers at a supermarket is provided below. Enter the data in L1 and test the alternate hypothesis that the average spent is more than $75.

98	79	151	38	116	55
42	61	88	64	120	93

Alternate hypothesis is _______________

p = __________

Decision is to _______________ the null hypothesis that µo=75.

Activity 2 Perform a two-small-sample hypothesis test for the population means.

The time in minutes to assemble a product using two different procedures is provided below. Enter Procedure 1's times into L1 and Procedure 2's times into L2. Test the alternative hypothesis that Procedure 1 provides higher times than Procedure 2. Pool the standard deviations for the test.

Procedure 1	54	61	58	56	63	52	60
Procedure 2	50	56	56	59	53	47	52

Alternate hypothesis is _______________

p = __________
