Chapter 3, Problem 3.8AC
The file MOBILESPEEO contains the overall download and upload speeds in Mbps for nine carriers the United States.
For the download speed and the upload speed separately:
- Calculate the
mean andmedian . - Calculate the variance, standard deviation,
range , and coefficient of variation. - Are the data skewed? If so, how?
- Based on the results of (a) through (c), what conclusions can you reach concerning the download and upload speed of carriers?

The following are suggested designs for group sequential studies. Using PROCSEQDESIGN, provide the following for the design O’Brien Fleming and Pocock.• The critical boundary values for each analysis of the data• The expected sample sizes at each interim analysisAssume the standardized Z score method for calculating boundaries.Investigators are evaluating the success rate of a novel drug for treating a certain type ofbacterial wound infection. Since no existing treatment exists, they have planned a one-armstudy. They wish to test whether the success rate of the drug is better than 50%, whichthey have defined as the null success rate. Preliminary testing has estimated the successrate of the drug at 55%. The investigators are eager to get the drug into production andwould like to plan for 9 interim analyses (10 analyzes in total) of the data. Assume thesignificance level is 5% and power is 90%.Besides, draw a combined boundary plot (OBF, POC, and HP)
