10. A printer manufacturing company claims that its new ink-efficient printer can print an average of 1500 pages of words documents with standard deviation of 60. Thirty-five (35) of these printers showed a mean of 1475 pages. Does this support the company's claim? Use 0.05% level of significance. Formulate the Null Hypothesis Test and Alternative Hypothesis Test. Ho: µ = 1500 Ha: p = 1500 O Ho: µ = 1475 Ha: p = 1475 O Ho: µ = 1500 Ha: µ > 1500 Ho: u = 1500 Ha: p < 1500

Question
10. A printer manufacturing company claims that its
new ink-efficient printer can print an average of
1500 pages of words documents with standard
deviation of 60. Thirty-five (35) of these printers
showed a mean of 1475 pages. Does this support
the company's claim? Use 0.05% level of
significance.
Formulate the Null Hypothesis Test and
Alternative Hypothesis Test.
Ho: µ = 1500 Ha: µ = 1500
Ho: µ = 1475 Ha: u z 1475
Ho: p = 1500 Ha: p > 1500
Ho: µ = 1500 Ha: µ < 1500
11. It is a decision making process for evaluating
claims about a population based on the
characteristics of a sample purportedly coming
from that population.
