Question

1) Given the data set below

       25 52 68 23 78 89 56 90 32 78

       45 48 62 54 94 69 46 79 40 33

       21 57 84 54 22 34 68 63 61 76

       87 78 39 50 70 60 32 65 73 45

       28 82 66 79 71 80 42 66 24 90

For the dada of Problem 1, find the approximate mean using the Frequency Distribution from problem 1

3) Find the Median of the data set from problem 1 using an arranged Stemplot

4) Find The mode from the data set in problem 1

5) Find the Midrange for the data set in problem 1

8) Given one dice and one quarter, what is the Probability of Tossing 6 on the dice and heads on the quarter

9) From a deck of 52 cards a card is drawn, what is the probability that the card is a King or a Red card?

Answer 1

Solution:

Mean = 58.56

Median = 61.5

Range = 73

Mode = 78

8. Probability of Tossing 6 on the dice and heads on the quarter is given by,

Probability = (Number of favourable cases) / (Total number of cases)

Required Probability = 1 / 12

9. Probability (Red card U King) is given by,

= (26/52) + (4/52) - [(26/52)*(4/52)]

Required Probability = 0.6153
