Use the Student's t distribution to find t for a 0.99 confidence level when the sample is 17. LA USE SALT\fWhat percentage of hospitals provide at least some charity care? Based on a random sample of hospital reports from eastern states, the following information is obtained (units in percentage of hospitals providing at least some charity care): 56.7 56.3 53.3 65.9 59.0 64.7 70.1 64.7 53.5 78.2 In USE SALT Assume that the population of x values has an approximately normal distribution. (a) Use a calculator with mean and sample standard deviation keys to find the sample mean percentage x and the sample standard deviation s. (Round your answers to four decimal places.) X S (b) Find a 90% confidence interval for the population average y of the percentage of hospitals providing at least some charity care.
