[example continued…] Scenario: I’m interested in whether there is a relationship between Team (A vs. B) and Outcome (Good vs. Bad). Below are the data.  Test the null hypothesis that the categories are independent.  α= .05. Team A Team B Good Outcome fo = 75 fe = fo = 45 fe = Bad Outcome fo = 25 fe = fo = 5 fe =   degrees of freedom, df = ______, and the Chi Square critical boundary = ______

[example continued…] Below is data for two variables, X and Y.  Answer the questions that follow.  X Y X-MX Y-MY (X-MX)2 (Y-MY)2 (X-MX)(Y-MY) 3 3 -2 -1 4 1 2 4 3 -1 -1 1 1 ___ 6 4 1 ___ 1 0 0 7 6 2 2 ___ 4 4   What is the missing value under the Y-MY column?  

A normal distribution has a mean of µ = 200 with σ = 20. If a vertical line is drawn through the distribution at X = 240, what proportion of the scores are on the left side of the line?

[example continued…] A researcher is interested in understanding the smartphone habits of college students in the US. To answer this question, the researcher conducts an online survey of 1000 randomly selected college students from California. 77% of these students reported using their smartphones as soon as they wake up in the morning. In this example, the 77% value reported by the college students in California is an example of a _________.

One of the major benefits of fusion imaging with PET and CT is:

A DNA segment contains three reporter genes (red, yellow, cyan), each flanked by unique, non-cross-reactive LoxP sites (black, gray, white). When Cre recombinase is activated, it randomly recombines matching LoxP sites, removing the intervening DNA. Based on this setup, determine for each of the following reporter gene combinations whether it could result (A) or could not result (B) from a single or series of such recombination events. Ignore the possibility of excised DNA reintegrating. Combination Can it occur? Red and yellow Red and cyan Yellow and cyan Cyan only Yellow only Red only
