a. What does a significance test tell us? When do you
use a 1 tailed t-test? When do you use a 2 tailed
t-test?
b. What is the difference between statistical
significance and effect size? What information does each of these
measures provide?
Question 3
Using the t-table
with = 18 degrees of freedom and a level of significance
of α=0.05, determine the critical value for the hypothesis test.
(Note: Since this is a left-tailed test, the critical value will be
negative). Enter your answer to three decimal places

-explain evaporation in terms of the Maxwellian velocity
distribution.
-How do the degrees of freedom in the equipartition of energy
relate to motion in monatomic and diatomic particles?
- What happens to ideal gases during an adiabatic compression or
expansion.
- When does entropy change in calorimetry(like when does it
increase, decrease or remain constant)?
- What is true for reversible, adiabatic processes in terms of
change in entropy, internal energy, heat and work?
The degrees of freedom for the F test in a one-way ANOVA, with n
observations and k independent samples, are:
Select one:
a. (n - 1) and (n - k)
b. (k - n) and (k - 1)
c. (k - n) and (n - 1)
d. (k - 1) and (n - k)
