Question: 54) Faced with rising fax costs, a firm issued a guideline that transmissions of 10 pages or more should be sent by 2 day mail instead. Exceptions are allowed, but they want the average to be 10 or below. The firm examined 35 randomly chosen fax transmissions during the next year, yielding a sample mean of 14.44 with a standard deviation of 4.45 pages.

(a) At the .01 level of significance, is the true mean greater than 10?

(b) Use Excel to find the right-tail p-value.
