Question

Suppose a simple random sample of size nequals=75 is obtained from a population whose size is Upper N equals N=25,000 and whose population proportion with a specified characteristic is p equals 0.6

1. Describe the sampling distribution of  p hat

2. Determine the mean of the sampling distribution

3. Determine the standard deviation of the sampling distribution

4. What is the probability of obtaining xequals=48 or more individuals with the​ characteristic? That​ is, what is ​P(ModifyingAbove p with caretpgreater than or equals≥0.640.64​)?

5. What is the probability of obtaining

xequals=3636

or fewer individuals with the​ characteristic? That​ is, what is

​P(ModifyingAbove p with caretpless than or equals≤0.480.48​)?
