The NBA "All-Time Player Directory" also gives the weight of each basketbal player. A random sample of 56 basketball players from the directory gave a sample standard deviation of s = 26.58 pounds for the weights of players. How many more basketball players from the "All-Time Player Directory" should be included in the sample to be 90% sure that the sample mean player weight x is within 4 pounds of the population mean p?
