If the distribution of intra ocular pressure (IOP) seen in 100 glaucoma patients has an average 30 mm with a SD of 10, what is the lower limit of the average
High-Yield Explanation
In the given question, Mean(u)=30 mm and SD=1.0 mm Thus,95% values are contained in the range of Mean+/-2 SD or 30+/-2(1) So, 95% values are contained in the range 30-2 mm and 30+2 mm OR between 28 and 30 mm.
