Extracted text: Suppose that the typing speed for secretaries are normally distributed with an unknown mean and standard deviation. A random sample of 26 secretaries is taken and gives a sample mean of 54 words per minute and a sample standard deviation of 5 words per minute. The ME, margin of error, for a 98% confidence interval estimate for the population mean using the Student's t-distribution is 2.44. Find a 98% confidence interval estimate for the population mean using the Student's t-distribution · Round the final answers to two decimal places. Provide your answer below: 98% of the x-values lie between | | and 11
