The weights of 1500 ball bearings are normally distributed with mean 22.40 and standard

deviation 0.048. If 300 random samples of size 36 each are drawn from this population,

determine the expected mean and standard deviation of the sampling distribution of

means, if Sampling is done with replacement.

How many of the random samples in the above problem would have their means between

22·39 and 22·41?

Solution†

Let’s represent the series in a different perspective,

Below are the positions,

Name Positions 1st 2nd 3rd

So, representation would be,

Positions

1 2 3 (Position's Alias/Naming)

1 5 8 = 76

2 7 3 = 25

3 4 9 = 89

4 5 7 = 69

5 3 8 = ?

Now, (by observation)

Take 1st and 3rd positions of each expression to make a number like this,

Number = 3rd position number (concatenate) 1st position number

e.g., if expression is 2 5 8 Then Number would be 82.

Then subtract 2nd position number from the Number would be 82 - 5 = 77.

Therefore,

By Observation,

5 3 8 = 85(Number) - 3 = 82

Answer = 82.

LETS TRY TO ANSWER THIS

FIRST OF ALL FIND THE LOGIC BEHIND IT

IF THE NUMBER ARE

Let a,b,c = d

Then c×10 -(b-a)=d

so now going by this logic we have

1,5,8=76

8×10-(5–1) =76

2,7,3=25

3×10 -(7–2)=25

3,4,9=89
