The filling machine inevitably experiences samples 12 jars of peanuts from the storage facility and measures their contents. The data are in the table Complete parts (a) through (d fluctuations in illing, so a quality-control manager randomly Click the icon to view the datatable (a) Are the given data normally distributed? (Check by constructing a normal probability plot) O Yes No (b) Determine the sample standard deviation The sample standard deviation is â–¡ oz (Round to three decimal places as needed) (c) Construct a 90% confidence interval for the population standard deviation of the number of ounces of peanuts. The lower bound is â–¡ oz. (Round to three decimal places as needed ) The upper bound is â–¡ oz (Round to three decimal places as needed ) (d) The quality control manager wants the machine to have a population standard deviation below 0 23 ounce Does the confidence interval validate this desie by Click to select your answer(s) . 0
