Problem 6E

In Example 5.20 (in Section 5.3) the following measurements were given for the cylindrical compressive strength (in MPa) for 11 beams:

38.43

 38.43

 38.39

 38.83

 38.45

38.35

 38.43

 38.31

 38.32

 38.48

 38.50

 

 

 

 

 

 

 

One thousand bootstrap samples were generated from these data, and the bootstrap sample means were arranged in order. Refer to the smallest value as Y1, the second smallest as Y2, and so on, with the largest being Y1000. Assume that Y25 = 38.3818, Y26 = 38.3818, Y50 = 38.3909, Y51 = 38.3918, Y950 = 38.5218, Y951 = 38.5236. Y975 = 38.5382, and Y976 = 38.5391.

a. Compute a 95% bootstrap confidence interval for the mean compressive strength, using method 1 as described on page 386.

b. Compute a 95% bootstrap confidence interval for the mean compressive strength, using method 2 as described on page 386.

c. Compute a 90% bootstrap confidence interval for the mean compressive strength, using method 1 as described on page 386.

d. Compute a 90% bootstrap confidence interval for the mean compressive strength, using method 2 as described on page 386.
