Which combination of factors is more likely to produce a small standard error? (No calculations are necessary). Group of answer choices: a.) σ = 5; n = 25 b.) σ = 10; n = 25 c.) σ = 5; n = 100 d.) σ = 10; n = 100

Suppose a simple random sample of size 50 is selected from a population with $\sigma=10$ . Find the value of the standard error of the mean in each of the following cases (use the finite population correction factor if appropriate). a. The population size is infinite. b. The population size is $N=50,000 .$ c. The population size is $N=5000 .$ d. The population size is $N=500$ .
'Which of the following samples will have the smallest value for the estimated standard error? n = 25 with 52 = 100 n = 25 with s2 = 400 n = 100 with 52 = 100 n = 100 with 52 = 400'

From a population that is not normally distributed and whose standard deviation is not known, a sample of 80 items is selected to develop an interval estimate for ðœ‡. Which of the following statements is true? The t distribution with 79 degrees of freedom must be used. The sample size must be increased in order to develop an interval estimate. The t distribution with 79 degrees of freedom must be used. The standard normal distribution can be used.
