    Question No: 21 ( Marks: 2 )
    Define the Null Hypothesis.


    ANS: Null hypothesis is a scenario which explain a given set of data. It is tested to determine whether data provides sufficient reasons to pursue some alternative hypothesis.
    It is a hypothesis that states there is no difference between 2 or more sets of data.

    Question No: 22 ( Marks: 2 )
    A coin can be tossed in 3 ways. A die can be thrown in 6 ways. A coin and a die together can be thrown in 3 X 6 = 18.ways.


    Question No: 23 ( Marks: 2 )
    Find harmonic mean (HM) of 10,12,14,17.
    ANS:
    Harmonic mean,HM = n/(1/x1 + 1/x2 + 1/x3 + 1/x4 + +1/xn)


    N= 4
    X1 = 10
    X2 = 12
    X3 = 14
    X4 = 17
    1/x1 + 1/x2 + 1/x3 + 1/x4 = 1/10 + 1/12+ 1/14+ 1/17 = 0.2385
    Harmonic mean = 4/0.2385= 16.77


    Question No: 24 ( Marks: 3 )
    Find proportion of bags which have weight in excess of 505 g.
    Mean = 500.
    StDev = 2.5 g
    (For z=2.00 probability is 0.4772)



    Question No: 25 ( Marks: 3 )
    Given for a frequency distribution mode = 18, mean = 21.Calculate median . Using these values comment on skewness of distribution.
    ANS:
    We know that,
    Mean-mode= 3(mean- median)
    Median= (2*mean+mode)/3
    Since,
    Mean= 21
    Mode= 18
    So,
    Median = (2*21+18)/3
    = (42+18)/3 = 60/3 = 10
    The distribution is Moderately skewed and unimodal distribution.



    Question No: 26 ( Marks: 3 )
    How many different ways can you select 2 letters from the set of letters: X, Y, and Z? (Hint: In this problem, order is NOT important; i.e., XY is considered the same selection as YX.)
    ANS:
    Total number of letters = 3
    Letters taken at a time = 2
    Number of ways in which 2 letters can be selected out of 3 = 3C2 = 3! / 2!(3-2)!
    =3*2*1/ 2
    = 3

    Question No: 27 ( Marks: 5 )
    How many possible permutations can be formed from the word MATHEMATICS?
    ANS:
    Total number of alphabets in mathematics = 11
    M = 2
    A = 2
    T = 2
    H = 1
    E = 1
    I = 1
    C = 1
    S = 1
    Permutations = 11! / 2! * 2! * 2! *1! * 1! * 1* 1! * 1!
    = 11! / 8 = 4,989,600
