Suppose you are going to test the hypothesis that two
populations have the same mean. You find sample averages of 6 and
7.5 and sample 1 has a standard deviation of 16 and sample 2 has a
standard deviation of 15 and both samples have 32 observations. In
this case the test statistic follows the t distribution with 61
degrees of freedom. True or False: you reject the null hypothesis
at the .01 level of significance. true or false

1. True or False? A ChiSquare distribution and a normal
distribution will always have the same shape?
2. What is the minimum value that a ChiSquare distribution can
have?
3. Which ChiSquare distribution has a higher peak; One that has
15 degrees of freedom or one that has 5 degrees of freedom.
4. True or False? If the differences between observed
values and an expected values are small, you will get a large
ChiSquare Statistic.
5. Explain in 4-6 sentences why...

(true or false), csc(x), cot(x), and tan(x) have the same
vertical asymptotes .

True or False: The higher the level of significance of a
hypothesis test, the stronger the evidence we require to reject the
null hypothesis.
True or False: The purpose of a hypothesis test is to assess the
evidence in favour of the null hypothesis.
True or False: The higher the p-value of a hypothesis test, the
more evidence we have to reject the null hypothesis.

True or False: The higher the level of significance of a
hypothesis test, the stronger the evidence we require to reject the
null hypothesis.
True or False: The purpose of a hypothesis test is to assess the
evidence in favour of the null hypothesis.
True or False: The higher the p-value of a hypothesis test, the
more evidence we have to reject the null hypothesis.
