Answer D,E,F only. Thank you. 

Answer (a).

Arrange the observations in ascending order.

The 55th percentile can be calculated as,

Pk=kn+1th100P55=5545+1100=25.3=25th+0.326th-25th=1049+0.3(1063-1049)=1053.2

The 9th decile can be calculated as,

Dk=kn+1th10D9=945+110=41.4=41th+0.442th-41th=1250+0.4(1250-1217)=1230.2

The 3rd quartile can be calculated as,

Qk=kn+1th4Q3=345+14=34.5=34th+35th2=1157+11572=1157

Answer (b).

The two observations 521 and 785 are deleted because these observations does not lie in given class interval.

The class width is calculated as,

class width=maximum-minimumnumber of intervals=1340-8017=77

According to class width the class intervals and frequency table is given as,

class interval frequency
801-878 5
878-955 11
955-1032 5
1032-1109 7
1109-1186 7
1186-1263 5
1263-1340 3

 

2. Consider the following data representing the life in hours of incandescent bulbs. 1,067 919 1,196 785 1,126 855 1,092 1,162 1,170 929 1,157 1,195 1,195 1,340 1,122 1,022 978 832 1,009 1,157 923 1,333 811 1,217 1,085 521 933 928 1,153 946 930 807 954 1,063 1,002 999 932 1,035 944 1,049 901 1,324 818 1,250 1,203 a. Using ungrouped data, find: P55, D9 and Q3. b. Use 7 intervals with the lowest starting at 801 hrs., and show the frequency distribution and cumulative frequency distribution. c. Create the frequency histogram based on (b). d. Create the frequency polygon based on (b). e. Create a stemand leaf plot or double stem and leaf plot. f. Create box plot.
