There is a histogram that goes with problems 13, 14, 15, and 16, but it doesn't show up in this file. There is a line that says "EMBED MtbGraph.Document.15" that I suspect is a placeholder for the actual graph.

Can you take a screenshot of the histogram and post the screenshot image as a separate file?

I can't answer #13 or #14 without the histogram.

Also, since these are multiple choice questions, do you just need the final answers, or do you need the steps taken to get the solutions?

Let me know if you can open and read file. I've added three more questions, hope you don't mind answering. I'll be sure to include additional $. Thanks again!

Conference responses:

1. The 15th percentile corresponds to a left tail area of 0.15. The corresponding z-value obtained from Excel is -1.0364. The IQ corresponding to the 15th percentile is then:

-1.0364 = (x - 100) / 16

x = 100 - (1.0364)(16)

x = 83.42

2. The 75th percentile corresponds to a right tail area of 0.25. The corresponding z-value obtained from Excel is 1.6745. The IQ corresponding to the 75th percentile is then:

1.6745 = (x - 100) / 16

x = 100 + (1.6745)(16)

x = 126.79

I'll post the solutions for the additional problems shortly.
