**7.**In a batch of 21 students eight were failed.The marks found by the successful students were 5,4,8,6,4,5,9,7,8,5,6 respectively. obtain out median of marks of all the students.

**8.**If the difference of 2 quartiles=32, sum of 2 quartiles=76, Median=48,then compute coefficient of skewness.

**9.**If (P.E)=0.025 and N=100,Find the value of correlation.

**10.**elaborate the components of a Time series?

**1**Locate the missing frequencies in the subsequent incomplete distribution when median is 45 Class Interval->(10-20),(20-30),(30-40),(40-50),(50-60),(60-70),(70-

**1.****80)**Total 230 Frequency-> 12,30,?,66,?,25,18

**1**obtain out the quartile coefficient of skewness from the subsequent data: Marks->(5-15),(15-25),(25-35),(35-45),(45-55),(55-

**2.****6**Frequencies->5,15,35,55,25,15

**5)****1**From the subsequent data,calculate the coefficient of correlation ranging from age of students and their playing habits: Age Group(yrs)->(15-16),(16-17),(17-18),(18-19),(19-20),(20-

**3.****2**No.of Students->200,270,340,360,400,300 Regular Players->150,162,170,180,180,120

**1)****1**Prepare price indeed number for the 3 years,taking avg. of 3 years price as base: Year->1,2,3 Wheat->100,99,99 Cotton->25,20,15 Oil->30,25,20

**4.****1**From the ahead data compute pattern values by the method of lowest squares and estimate the value of expected production in 2006-07 Years->(2000-01),(2001-02),(2002-03),(2003-04),(2004-0

**5.****5)**Production(Lakh Tons)->83,92,71,90,169
