Question

Does the interval suggest that 109 is a plausible value for the true average work of adhesion for UHPC adhered to steel? The interval suggests that 109 is a possible value for the true average. The interval doesn't suggest that 109 is a possible value for the true average. Does the interval suggest that 112 is a plausible value for the true average work of adhesion for UHPC adhered to steel? The interval suggests that 112 is a possible value for the true average. The interval doesn't suggest that 112 is a possible value for the true average. (c) Predict the resulting work of adhesion value resulting from a single future replication of the experiment by calculating a 95% prediction interval. (Round your answers to two decimal places.) 1 mJ/m2 Compare the width of this interval to the width of the CI from (b). The CI is wider than the PI. The two intervals are the same width. The PI is wider than the CI. Correct: Your answer is correct. (d) Calculate an interval for which you can have a high degree of confidence that at least 95% of all UHPC specimens adhered to steel will have work of adhesion values between the limits of the interval. (Round your answers to two decimal places.) , mJ/m2

Explanation / Answer

Solution-

Confidence interval gives you a certain range where we can know the occurrence of some probable values to a certain extent. To know whether 109 is a plausible value, we will check if 109 lies in the given confidence interval .

If it lies then we can say that 109 is a plausible value, otherwise not.

Same would happen for the value of 112, To know whether 112 is a plausible value, we will check if 112 lies in the given confidence interval .

If it lies then we can say that 112 is a plausible value, otherwise not.

TY!
