Hello students, we are asked in the question a company pays its employees an average weighs of 3 .25 hour with standard deviation .6.
00:11
So in the question we are asked if the wages are normally distributed determine the minimum weight of highest 5%.
00:17
So normal distribution is given here if i write here normal distribution is given.
00:25
So what happens in normal distribution? all the random variables are distributed amongst a well shaped curve.
00:34
So this is something like this.
00:37
So all the random variables are distributed amongst well shaped curve.
00:41
This is j and left inside this is minus z.
00:45
So basically this is j and this is minus j and this is b jr.
00:50
So total probability means all probability sum is equivalent to one.
00:56
And total area under normal curve is always equal into 1.
01:00
It means right -hand side area is 0 .5 and left -hand side area is also 0 .5.
01:07
It is having z -score attribute which is x minus mu divided by sigma...
