They are separate questions. A variable s increased by 2:
The sum of a and b:
c minus the sum of a and b :
z increased by 12
t minus the sum of s and 5:
The sum of 15 and d then decreased by c:

Arandom sample of size n 64 is taken from a population with population proportion p 0.38 describe the sampling distribution of p. draw a graph of this probability distribution with its a. mean and standard deviation. b. what is the probability that the sample proportion is greater than 0.5? what is the probability that the sample proportion is less than 0.3? d. what is the probability that the sample proportion is between 0.35 and 0.45?
