Suppose Y=37 measured correct to the nearest 0.5 degree, what is the interval estimate for Y?
Interval estimate is basically the upper and lower band. Eg./ 55
X = 31 the number is closer to 31 than to 30 or 32 ...
30.5 < X < 31.5 ... note...if you have 31.7 rounded to the nearest degree... it would become 32.
36.75 < Y < 37.25 for the next one..
upper bound = 37.25
lower bound = 36.75...
to get these... halve your increment...

so the upper band for 55 is S?
To get to the nearest degree you could not go more than half way to the next or previous.?

Answer is:
30 ≤ X ≤ 32
Lower band = 30
Upper band = 32
*********************
36.5 ≤ Y ≤ 37.5
