Unformatted text preview: answer there is sufficient evidence at the 0.02 level to support the alternative hypothesis percentage is not 73% answer there is not sufficient evidence at the 0.02 level to support the alternative hypothesis percentage is not 73% answer there is not sufficient evidence at the 0.02 level to support the alternative hypothesis percentage is over 73% answer there is sufficient evidence at the 0.02 level to support the alternative hypothesis percentage is less than 73% answer there is not sufficient evidence at the 0.02 level to support the alternative hypothesis percentage is over 73% answer there is sufficient evidence at the 0.02 level to support the alternative hypothesis percentage is less than 73% Using traditional methods it takes 107 hours to receive an advanced driving license. 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. Anew training technique using Computer Aided Instruction (CAI) has been propsed. reject the null hypothesis at a 0.02 level of significance answer: there is sufficient evidence at the 0.02 level to support the alternative hypothesis that the new technique reduces training time Using traditional methods it takes 107 hours to receive an advanced driving license.

A new training technique using Computer Aided Instruction (CAI) has been propsed. reject the null hypothesis at a 0.02 level of significance answer: there is sufficient evidence at the 0.02 level to support the alternative hypothesis that the new technique reduces training time Ho p <= .33 Ha p > .33 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 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 <= 5.3 Ha > 5.3 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....
