A random sample of size n = 71 is taken from a population of size N = 639 with a population proportion p = 0.73.

a-1. Is it necessary to apply the finite population correction factor?

a-2. Calculate the expected value and the standard error of the sample proportion. (Round "expected value" to 2 decimal places and "standard error" to 4 decimal places.)

b. What is the probability that the sample proportion is less than 0.66? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

Expert Solution

Finite correction factor

If n/N is less than 0.05, The finite correction can be ignored

If n/N is greater than 0.05, The finite correction must be used.

1. A random sample of size n = 10 is taken from a large population. Let μ be the unknown population mean. A test is planned of H0: μ=12vs. HA: μ̸=12usingα=0.1. A QQ plot indicates it is reasonable to assume a normal population. From the sample, x̄ = 14.2 and s = 4.88. (I suggest doing this problem with a calculator and table as practice for exams. You may check your answers with R if you wish.) (a) Since the...
