stocks and 32 NASDAQ stocks and complete the following statements.
In words, define the Random Variable. ____________=
The distribution to use for the test is:
Calculate the test statistic using your data.
Draw a graph and label it appropriately. Shade the actual level of significance.
Graph:
Calculate the p-value:
Do you reject or not reject the null hypothesis? Why?
Write a clear conclusion using a complete sentence.
Decreasing stocks survey
Randomly pick 8 stocks from the newspaper. Using two consecutive days’ business
sections, test whether the stocks went down, on average, for the second day.

Candy survey
Buy three small packages of M&Ms and 5 small packages of Reese's Pieces (same net weight as the M&Ms). Test whether or not the mean number of candy pieces per package is the same for the two brands.
