Question
Describing, Exploring, and Comparing Data In Exercises 17-20, use the following cell phone airport data speeds (Mbps) Percentiles. from Sprint. Find the percentile corresponding to the given data speed. 0.2 0.3 0.3 0.3 0.3 0.3 0.3 0.4 0.4 0.4 0.5 0.5 0.5 0.5 0.5 0.6 0.6 0.7 0.8 1.0 1.1 1.1 1.2 1.2 1.6 1.6 2.1 2.1 2.3 2.4 2.5 2.7 2.7 2.7 3.2 3.4 3.6 3.8 4.0 4.0 5.0 5.6 8.2 9.6 10.6 13.0 14.1 15.1 15.2 30.4 Tali 17. 2.4 Mbps 18. 13.0 Mbps 19. 0.7 Mbps 20.9.6 Mbps In Exercises 21-28, use the same list of Sprint airport data speeds (Mbps) given jor Exercises 17-20. Find the indicated percentile or quartile. 21. Ps 22.QExplanation / Answer
Ans:
Total observations=50
17)There are 29 observations below 2.4,so corresponding percentile=(29/50)*100=58th percentile
18)There are 45 observations below 13,so corresponding percentile=(45/50)*100=90th percentile
19)There are 17 observations below 0.7,so corresponding percentile=(17/50)*100=34th percentile
20)There are 43 observations below 9.6,so corresponding percentile=(43/50)*100=86th percentile
21)60th percentile=P60
0.6*50=30,means that there wil be 30 observations below it.
P60=2.5
22)Q1=first quatule i.e. 25% of data falls below it.
0.25*50=12.5,means there will be approximately 12 observations below it
Q1 will be =(0.5+0.5)/2=0.5
