Question

The mean of the following distribution is 26. Find the value of p and also the value of the observation.

xi 0 1 2 3 4 5
fi 3 3 p 7 p - 1 4
Also, find the mode and the given data.

Answer 1

Answer:

Step-by-step explanation:

Given  

The mean of the following distribution is 26. Find the value of p and also the value of the observation. xi 0 1 2 3 4 5

                                                xf 3 3 p 7 p - 1 4 Also

 Now we know that

   Mean = Sum of observation / Number of observations

     26 = 3 + 3 + p + 7 + (p – 1) + 4 / 6

      16 + 2 p = 156

        2 p = 156 – 16

        2 p = 140

         P = 70  

Now value of observations will be 3, 3, 70, 7, (70 – 1), 4

                             = 3, 3, 70, 7, 69, 4

Also Mode is 3, since it occurs most .

Answer 2

Answer:

The value of x is 70 ...

And, the mode is 3..

Step-by-step explanation:

Mean = sum of all observation/total no. of

observations...

26 = 3+3+p+7+(p-1)+4/6

156= 16+2p

2p = 156 - 16

2p = 140

p = 140/2

therefore the value of p = 70...

the observation= 3 , 3 , 70 , 69 , 4...

and mode is 3 as it is occurring the most often....

Hope this will help u...
