hypotheses and z-score

In this
assignment, you will demonstrate your ability to write hypotheses with
the correct directionality and to correctly solve problems related to
Z-scores.

In Part 1
you will be presented with several relationships and will be asked to
write out the null and alternative hypotheses in the proper form. In
this section you will:

Indicate the directionality of the relationship and what are being compared.
Write the null hypothesis (remember, this is in terms of the population).
Write the alternative hypothesis (remember, this is in terms of the samples).

In Part 2
you will be given a series of questions regarding a normal
distribution, you will be asked to either determine the percentage above
or below particular raw scores; or to calculate the raw score that will
correspond to a particular percentage. For each question:

Write out your calculations.
Draw your normal curve- include the mean location, your score(s) location(s), and shade the area(s) you are looking for.
The % from the normal curve table.
The final answer.
