1. Statistics are used to infer something about the __________________.

2.A population has mean μ = 19 and standard deviation σ = 5. A random sample of size n = 64 is selected. What is the probability that the sample mean is less than 18?

3.A population has mean μ = 16 and standard deviation σ = 2.0. A random sample of size n = 36 is selected. What is the probability that the sample mean is greater than 16.8?

4.The proportion of students that have taken the census is π = .7, what is the probability that a sample of size 50 yields a sample proportion of .75
