1. 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. Specify the level of significance. 6. 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. Forty-nine (49) of these printers showed a mean of 1475 pages. Does this support the company's claim? Use 0.05% level of significance. Compute the test statistics.
