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.
4 out of 52 because there are 52 cards in a deck but only 4 kings therefore it would be 4 king out of a deck of 52
Y=15x+45
150=15x+45
-45 -45
105=15x
105/15=15x/15
