Recorded here are the germination times (in days) for eleven randomly chosen seeds of a new type of bean 15, 16, 17, 19, 20, 15, 13, 13, 14, 11, 18 Send data to calculator Send data to Excel Assuming that germination times are normally distributed, find a 90% confidence interval for the mean germination time for all beans of this type. Then find the lower limit and upper limit of the 90% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: Upper limit: X ?
