T-Test Problems (show your work)

A researcher wishes to determine if a particular drug affects pilot reaction time to air traffic controller instructions. The researcher has 10 pilots. The pilots are observed in normal performance and their reaction times are recorded. Then the pilots are administered the drug, observed again, and their reaction times are recorded. The expectation is that the drug will reduce reaction time.

Pilot	Trial 1 Time (sec)	Trail 2 Time (sec)
A	.83	.69
B	.74	.71
C	.82	.79
D	.86	.87
E	.66	.65
F	.63	.68
G	.81	.67
H	.77	.72
I	.73	.71
J	.69	.65

A researcher wishes to learn if a certain drug affects the reaction time of dispatchers to emergency calls.She obtained independent simple random samples of dispatchers from a population assumed to be normally distributed,and randomly divided them into two groups.She then had one group take the drug and used the second group as a control. Dispatchers were seated at workstations and directed to respond to pseudo-emergency calls.The researcher collected each dispatcher’s reaction time over 100 trials and calculated the mean for...

(a) A researcher wishes to test the performance of two paper shredders, the Stanley and the Bosch, designed for professional use. Each of 10 randomly selected volunteers shredded 100 sheets of paper with the Stanley, and then another sample of 10 randomly selected volunteers each shredded 100 sheets with the Bosch. The Stanley took an average of 203 seconds to shred 100 sheets with a standard deviation of 6 seconds. The Bosch took an average of 187 seconds to shred...
