Recorded here are the germination times (in days) for twelve randomly chosen seeds of a new type of bean: 13, 19, 22, 20, 12, 14, 16, 22, 21, 12, 16, 21 Assuming that germination times are normally distributed, find a  90%  confidence interval for the mean germination time for all beans of this type. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) What is the lower limit of the confidence interval?   What is the upper limit of the confidence interval?
