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
