Complete parts ?(a) through ?(c) below. ?(a) Determine the
critical? value(s) for a? right-tailed test of a population mean at
the ? = 0.10 level of significance with 20 degrees of freedom. ?(b)
Determine the critical? value(s) for a? left-tailed test of a
population mean at the ? = 0.05 level of significance based on a
sample size of n = 15. ?(c) Determine the critical? value(s) for a?
two-tailed test of a population mean at the ? = 0.10...
Identify the critical z values and the rejection region of the
following:
a) Right-tailed test with a = 0.05
b) Left-tailed test with a = 0.025
c) Two-tailed test with a = 0.01
d) a = 0.10 with HA : p < 0.26
2) For a one-tailed hypothesis using a z-distribution, find the
critical value (z-score) that will give you a critical region with
an alpha of the following values:
a) alpha = 0.20
b) alpha = 0.10
c) alpha = 0.05
d) alpha = 0.01
e) alpha = 0.001
Using the z table (The Standard Normal Distribution Table), find
the critical value (or values) for the two-tailed test with
a=0.05
. Round to two decimal places, and enter the answers separated
by a comma if needed.
