Astronauts increased in height by an average of approximately 40 mm during the apollo-soyuz missions, due to the absence of gravity compressing their spines during their time in space. to find out if something similar happens on earth, a nasa experiment measured the heights of six men immediately before a three day bed rest. by the end of the third day, they had increased in height by an average of 14 mm, with a standard deviation of 0.66 mm. find the 95% confidence interval for the change in height after 3 days of bed rest. express your answer as lower bound to higher bound with one decimal place. do not include units.
