Anew training technique using Computer Aided Instruction (CAI) has been propsed. reject the null hypothesis at a 0.02 level of significance that the new technique reduces training time Using traditional methods it takes 107 hours to receive an advanced driving license.

The company's promtional literature claimed that Ho p= .33 Ha p =/ .33 a sample of 1200 computer chips revealed that 36% of the chips do not fail in the first 1000 hours of their use. The company's promtional literature claimed that Ho p>= .33 Ha p < .33 An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 260 egines and the mean pressure was 5.4 lbs/square inch. assume the standard seviation is known to be 0.8. if the valve was designed to produce to produce a mean pressure of 5.3 lbs/square inch, is there sufficient evidence at the Ho μ <= 5.3 Ha μ > 5.3 An engineer has designed a valve that will regulate water pressure on an automobile engine.
