Cable TV choices: A telecommunications company provided its cable TV subscribers with free access to a new sports channel for a period of one month. It then chose a sample of 415 television viewers and asked them whether they would be willing to pay an extra $10 per month to continue to access the channel. A total of 25 of the 415 replied that they would be willing to pay. The marketing director of the company claims that less than 10% of all its subscribers would continue subscribing. Can you conclude that the director's claim is true? Use the a=0.01 level of significance with the P-value method and Excel.
