Question

Your claim results in the following alternative hypothesis:
H_a : μ ≠≠ 166
which you test at a significance level of α=.02α=.02.

Find the positive critical value, to three decimal places.

z_α/2 =

You are performing a right-tailed t-test with a sample size of 5

If α=.005α=.005, find the critical value, to two decimal places.

You are performing a two-tailed test.

If α=.06α=.06, find the positive critical value, to three decimal places.

z_α/2 =

Testing:

H0:μ=7.83H0:μ=7.83
H1:μ>7.83H1:μ>7.83

Your sample consists of 23 subjects, with a mean of 8.3 and a sample standard deviation (s) of 4.14.

Calculate the test statistic, rounded to 2 decimal places.

t=t=

You are performing a two-tailed z-test

If α=0.1α=0.1, find the positive critical value, to two decimal places.
