On a television show, eight contestants try to lose the highest percentage of weight in order to win a cash prize. As part of the show, the contestants are timed as they run an obstacle course. The table shows the times (in seconds) of the contestants at the beginning of the season and at the end of the season. At
α=0.05 is there enough evidence to support the claim that the contestants' times have changed? Assume the samples are random and dependent, and the population is normally distributed. Complete parts (a) through (e) below.

C. Calculate dBAR and Sd.
(d) Find the standardized test statistic t.
E. (e) Decide whether to reject or fail to reject the null hypothesis and interpret the decision in the context of the original claim.

It has been suggested that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the length of stay of a trip for pre-and post-retirees. A sample of 697 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below.
| number of nights | pre-retirement | post-retirement | total |
| 4-7 | 241 | 175 | 416 |
| 8-13 | 78 | 72 | 150 |
| 14-21 | 30 | 60 | 90 |
| 22 or more | 11 | 30 | 41 |
| total | 360 | 337 | 697 |
With this information construct a table of estimated expected values.
| number of nights | pre-retirement | post-retirement |
| 4-7 | ||
| 8-13 | ||
| 14-21 | ||
| 22 or more |
Now, with that information, determine whether the length of stay is independent of retirement using α=0.01.
(a) Find test value χ2=
(b) Find the d.f.:
(c) Find the critical value:
(d) The final conclusion is
A. There is not sufficient evidence to reject the
null hypothesis that the length of stay is independent of
retirement.
B. We can reject the null hypothesis that the
length of stay is independent of retirement and accept the
alternative hypothesis that the two are dependent.

A recent census asked respondents to state the highest level of education that they had received. The responses were 39% High school, 45% TAFE or Undergraduate Degree, 13% Higher Degree and 3% Other.
The mayor of a small country town held a similar survey. Below are observed counts for each of the education levels for 250 respondents from the town: Highest Education Level
|
Highest education level |
Observed count |
|
High school |
115 |
|
Tafe or uni |
105 |
|
Higher degree |
20 |
|
Other |
10 |
a) If the counts observed for the town matched that of the census, what would be the expected counts for
each education level?
b) To see if these results are unusual, should you perform a goodness-of-fit test or a test of independence?
c) State your hypotheses.
d) How many degrees of freedom are there?
e) Find x2 and the P-value.
f) State your conclusion (use α = 0.05) in the context of the question.
