In computing the range Lower Limit < E (or so-called margin of error) LL = UL = X Illustrative Example: A random sample of 52 scores from the examination is taken and it gives a sample mea 82 with the interval scores between 81.18 and 83.82 having a 90% level of confidence. e. Confidence Interval 81.18 < M <83.82 a. n= 52 b. 82 c. UL = 83.82, LL = 81.18 f. Confidence Level = 90% d. E = UL -i = 83.82-82 = 0.82 PROBLEM SOLVING: Write your answer on the Space provided. You may use additional sheet if necessary. A sample mean of 13 meters was taken from the sample of 95 Iron rod bars that will be used in construction with the interval length between 15.2 meters and 10.8 meters with 95% level of confidence.

Illustrative Example: Solve the length of interval using the following s10.24 Za 2.898 n=17 Solution: Length = 10.2 =2(2.898)(- ) = 5.796(2.484) = 14.40 PROBLEM SOLVING: Write your answer on a separate sheet. Show all your solutions. Solve the length of confidence interval using the following given. 1.) n = 22 s= 6.87 Za = 2.508 2.) n=16 s= 11.16 Za = 2.11991 3.) n= 21 s= 8.04 Za = 3.8193 %3D
