Answer 1

Given interval is, 28 Upperbound. دار) Lower bound O Margin af interval e mor width af 2 (25-21) 4 2 = 2 2 .. emoy = 2 of mean (4) is Sample wean Margin of The point estimate population lagjie, Iů = 2]. So, we need to find ł. interval is, The formula for the construction ł I Margin af There Subtraction the get and add lower bound the get upper and lower bound is given of enor when we nake we will when we we upper bound. (21, 25) as t + Margin af enor = (21,25)

ā MOE = 21 Mot! Margin af error x + MOE = 25 the will Both the equation same value give best point estimate is unique. the 2 = 21 X = 21+2 = 23 or ŭ + MOE =25 ł + 2 =25 x - 25 - 2 = 23 x = 23 G point estimate.
