An average computer mouse inspector can inspect 60 mice per hour with a population standardx deviation of 10 mice per hour. The 48 computer mice inspectors at a particular factory can only inspect 55 mice per hour. Does the company have reaseon to believe that these inspectors are slower than average at a = 0.10?

Possible answers:

yes, because the tst value -3.46 falls in the noncritical region.

no, because the test value -1.98 falls in the critical region.

yes, becasue the test value -3.46 falls in the critical region.

no because the tst value -1.98 falls in the noncritical region.
