For a standard normal distribution (m = 0, σ = 1) find the probabilities:

a. z falling between -1.96 and +1.96
b. z falling above 1.64
c. Falling below -1.96
d. Falling above -1.96

The four general type of research design are secondary, experiment, observation and survey. Give one advantage and disadvantage of each.

3. (3 points)
What are the four “levels of measurement�? Give an example of each explaining why the example fits the definition.

You have been awarded a grant to study “The effects of early intervention on reading ability of elementary school children struggling with reading.�

Using at least three of the “descriptors of research design� describe how you would design the study.

(Two or three paragraphs will be sufficient --- this could be a 35 page report!)

I don't know whether the rest concern pure maths but you should at least try the first question. You don't even have to convert the values given into the z-scores, but apply them directly and look up the probabilities, and add/subtract depending on the situation. Post what you get! :)
