Question

Complete parts (a) through (c) below.

(a) Determine the critical value(s) for a right-tailed test of a population mean at the

alphaequals=0.100.10

level of significance with

2020

degrees of freedom.

(b) Determine the critical value(s) for a left-tailed test of a population mean at the

alphaequals=0.100.10

level of significance based on a sample size of

nequals=1010.

(c) Determine the critical value(s) for a two-tailed test of a population mean at the

alphaequals=0.010.01

level of significance based on a sample size of

nequals=1717.

All Criticals values are calculated using t table

a) The critical value for right tailed test at 10% significance level and 20 df is 1.3253

b) Sample size n = 10, df = 9

The critical value for left tailed test at 10% significance level and 9 df is -1.383

c) Sample Size n = 17, df = 16

The critical value for two tailed test at 1% significance level and 16 df is (-2.921, 2.921)
