Answer:
Pa - Pb
Step-by-step explanation:
The mean of the distribution of sample differences will always be the difference between the population proportion, That is ; Pa - Pb ; This is because according to the central limit theorem which says the sampling distribution of sample means approaches a normal distribution as sample size gets larger irrespective if the shape of the Population distribution. Hence, the distribution of sample differences will follow a normal distribution and the mean will Hence be the difference in the population mean.
Answer:
The answer is (4,2)
Step-by-step explanation:
in the point (-4,5) X=-4 AND Y=5
so if you move 8 units right, the X increases by 8(because the the x axis is left and right) so X transform into 4= -4+8=4
With Y(the y axis is up and down) whe u go 3 units down un decrease the number so Y transforms into 2== 5-3=2
The new coordiantes are(4,2)
56 different sub-committees are possible
Step-by-step explanation:
When the selection has to be made without order, combinations are used.
The formula for combination is:
Here,
Total members = n = 8
Members to be selected = r = 5
So,
Hence,
56 different sub-committees are possible
