Question
alues that form the boundaries of the Find the crituf the following sample sizes: each of the tw a, n=6 b.n=12 c, n = 24 egion for a two-tailed test with = Or le of n 6 scores was obtained a population with unknown parameters. Scores: 7, 1, 6, 3, 6, 7 ute the sample mean and standard deviation. te that these are descriptive values that (No summarize the sample data.) b. Compute the estimated standard error for M. (Note that this is an inferential value that describes how accurately the sample mean represents the unknown population mean.)Explanation / Answer
Question 5:
a) Here, for n-1 = 5 degrees of freedom, we get from the t-distribution tables that:
P( -2.571 < t5 < 2.571 ) = 0.95
Therefore the critical values here are - 2.571, 2.571
b) Here, for n-1 = 11 degrees of freedom, we get from the t-distribution tables that:
P( -2.201 < t11 < 2.201 ) = 0.95
Therefore the critical values here are - 2.201, 2.201
c) Here, for n-1 = 23 degrees of freedom, we get from the t-distribution tables that:
P( -2.069 < t23 < 2.069 ) = 0.95
Therefore the critical values here are - 2.069, 2.069
