Recorded here are the germination times ( in days) for 10 randomly chosen seeds of a new type of bean.

16, 12,20, 13,14,11,21,15,22,11

Assuming that germination times are normally distributed, fid a 95% confidence interval for the mean germination time for all beans of this type.

Give the lower limit and higher limit of the 95% confidence interval.

Carry your intermediate computations to at least 3 decimal places.

Round answer to 1 decimal place.
