Question

Data generating code (DGC): It consists of first non- zero digit and the last digit of your K-ID. Please write down your two digit DGC here: DGC (GOOD GRADES NEED HARD WORK) The following are the scores of 11 students in Biostatistics during the last semester Score 3041 58 69 7777 99 86 72 2571 Create a new variable: Scrambled Score (SS) - DGC +Score. SS For the scrambled score data, do the following (a) Arrange the scrambled data in ascending order: (b) Xmax = (c) Xmin= (d) 02 = (e) 0,= (03- (g) IQR= (h) STEP (1) LIFT () UIF (k) Xs= (/) X;= (m) Is there any outlier? (n) What is the distribution of the scores?

DGC = 49

Answer 1

→ solution, given that, DOC= 49 score 30 41 SS = DGC + score 79 go 107 Loc 118 I won it or o hd 126 126 148 rrrrrrrrrrIIIIIIIIIIII1111111111 135 opa Le 121 174 120 키 © → coranged ss data in ascending order 74179,90,107,1181120,121,1261126 , 135, 148

b) xmax= maximum value of ss data = 148 ③ xmin = minimum value of ssdata = 74 @ @2= median n= 1 Therefore, odd @2= Digth obsn (1+1th obsn = 8th obsn - @2= 120 e Q1 = lower Quad tile = middle value of lower half

Therefore i median 741 79, go, 107, 118 (120) 121, 1261 1261 lower half upper 135, 148 half Therefore, @ 1= middle value of lower half = go @ @ @3= middle value of upper belf = 126 © for - 03 - 01 = 126 - go IOR = 36

J LIF = Lower inner pense = @1 - 1-5 (SOR) = go- 15( 36 ) LIF = 36 O UIF= Upper inner pense = Q3 + 1.5 CIOR) = 126 + 1.5 (36) UIF = 180 Octlies are calculare using obervation < LIF and obseovation > UFF are ocetler LIF= 36 and UIF = 180 Now, from the ss dara all obsn e [361180]

Therefore there is no outier in data distoibretion. 170 160 150 140 130 120 1 2 3 4 5 6 7 8 9 10 Therefore the distribletion is negatively skewed& and it is distributed as CXip(x)) . prob. of each score is also prob. distribution for scores-
Sorry I don't know what is exactly STEP, X's and Xj. I can tried very much for this but I don't know what is exactly meaning of these but other than that all that I have solved is correct. Go throught the solution.

Thankyou
