The t-chart only has certain values for degrees of freedom
(n=1-30, 40,50,…,120, ∞). If the degrees of freedom you are looking
for does not appear on the chart, go to the LOWER value on the
chart. For example, if you have 47 degrees of freedom, use the
corresponding t-values for 40 degrees of freedom. This is
considered a “conservative solution.” Why do you think you would
use the LOWER degrees of freedom and not the HIGHER value?

If we know the population standard deviation, we can use which
table to do a hypothesis test?
Group of answer choices
Z-table
T-table
Critical table
Significant table
In the critical value approach, to make a decision, we compare
the critical value with the:
Group of answer choices
Test statistic
p-value
Hypothesized value
Population parameter
In the critical value approach, if we are doing a two-tailed
test, we do not know the population standard deviation, and we find
that the test...
