Class mid-mark or Class mark
is the mid-point of each interval. Class mark for Class (11 - 15) is . Similarly, class marks for other intervals are 18, 23, 28 When the data is put in a frequency distribution table, the marks obtained by an individual has lost its meaning. Thus some details have been lost. But we ..

Eleven Genetic Variations Linked To Type 2 Diabetes - ScienceDaily (Oct. 19, 2009) — Mathematicians at Michigan Technological University have developed powerful new tools for winnowing out the genes behind some of humanity’s most intractable diseases. See Also: Health & Medicine Diabetes Genes Parkinson's Research Computers & Math Software Computer Modeling Statistics Reference Computational genomics DNA microarray Human Genome Project Sex linkage With one, they can cast back through generations to pinpoint the genes behind inherited illness. With another, they have isolated 11 variations within genes—called single nucleotide polymorphisms, SNPs or 'snips'—associated with type 2 diabetes. 'With chronic, complex diseases like Parkinson's, diabetes and ALS [Lou Gehrig's disease], multiple genes are involved,' said Qiuying Sha, an assistant professor of mathematical sciences. 'You need a powerful test.' That test is the Ensemble Learning Approach (ELA), software that can detect a set of SNPs that jointly have a significant effect on ....

  #11 Go Figure Applying Statistics#11 Go Figure Applying Statistics Thepurpose of Go Figure? is to help students review for the mathematics section of the Grades 5-7 Ohio Academic Achievement Tests. The topics covered by the project address critical objectives found in the tests, but more importantly, they address those items that are frequently missed by students. Pythagleo drops several reports labeled 'Government Agencies Attempting to Suppress the Study of Phenomena' as he runs to avoid Carter and Chris. Chris and Carter study the reports and other data they find as they continue trying to solve the mysterious disappearance of the Etna High students in 1966. Pythagleo denounces any government involvement but Chris finds a folder marked 'Etna High Test Subjects', 'Confidential', and 'FBI'.

Question : 1) Let a card be selected from an ordinary deck of playing cards. The outcome c is one of these 52 cards. Let X(c) = 4 if c is an ace, let X(c) = 3 if c is a king, let X(c) =2 if c is a queen, let X(c) =1 if c is a jack, and let X(c) = 0 otherwise. Suppose that P assigns a probability of 1/52 to each outcome c. Describe the induced probability P_x(D) on the space D= {0,1,2,3,4} of the random variable X. 2) Consider an urn which contains slips of paper each with one of the number 1,2,...,100 on ..

Answer : PX(1) = 4/52 ; PX(2) = 4/52 ; PX(3) = 4/52 ; PX(4) = 4/52 [4/52 = 1/13] ; PX(0) = 36/52 or 9/13 If there are I slips for the I-th number, the total number of slips in the urn is 1+2+3+...+99+100 = 5050. So, the chance of drawing I is I/5050. What is the sum of the numbers 1 through N? N(N+1)/2 This should give you a clue to the second part of the question.
