8 9 10 11 12 13 14 15 16 17 18 19 Recorded here are the germination times (in days) for twelve randomly chosen seeds of a new type of bean. 16, 19, 13, 11, 17, 18, 22, 21, 22, 17, 13, 12 Send data to calculator Assuming that germination times are normally distributed, find a 95% confidence interval for the mean germination time for all beans of this type. Then find the lower limit and upper limit of the 95% 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: Il X 5 Upper limit
