Extracted text: A simple random sample of size n = 18 is drawn from a population that is normally distributed. The sample mean is found to be x = 23.9 and the sample standard deviation is found to be s = 6.6. Determine if the population mean is different from 26 at the a = 0.01 level of significance. Complete parts (a) through (d) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). Click here to view the table of critical t-values. ..... (a) Determine the null and alternative hypotheses. Ho: H 26 = H,: H 26 (Type integers or decimals. Do not round.) (b) Identify the test statistic. (Round to two decimal places as needed.)
