LUSE SALT (a) How many degrees of freedom are present in this study? 7 (b) What is the point estimate (in days)? days What is the standard deviation (in days) of the sample? (Round your answer to four decimal places.) days (c) What is the 95% confidence interval (in days) for the population mean? (Use a table or technology. Round your answers to three decimal places.) days (d) Interpret the 95% confidence interval for the population mean. O We know that 95% of the results will be in the interval. O Ninety-five percent of the data are outside of the interval. O We are 95% confident all results are in this interval. We are 95% confident that the true mean is contained in the interval.
