Aronson et al. (1991) asked sexually active college students to write a speech advocating condom use. Their study had a 2 (condom advocacy speech: written vs. written and recorded a video for high school students to watch) x 2 (salience of personal failures to use condoms: low vs. high). Several months later, Pp who wrote and recorded the speech and for whom salience of failures to use condoms was ____ reported the most frequent use of condoms.

You have 100 elements (in this case, 100 e-mail addresses) stored in a vector, and you want to repeat a function in R for each one.  Which loop would be appropriate in this case?

When this R script is run, what is the fourth string what will be printed?  (This is a nested loop.  Also, “paste” is used to concatenate strings.)

What happens if you complete the following using R? First, you execute this statement: Then, you provide the number 2, when input is requested in the console. Finally, you execute this statement:

A data analyst at a construction materials manufacturer is working on a project for one of their products.  During that time, she performs regression analysis and receives the following output from her software tool.  Based on the output, density should be removed from the regression model.  

Regression analysis is used to generate an equation that will predict how the density of particleboard affects its stiffness.  Based on the following results from the analysis, if the value for “density” is 28, what would be the predicted “stiffness”?  

The magnitude of the Discrete-time Fourier transform (DTFT) of  x(n)=  

A sampling rate change by a noninteger factor of 5/6 is implemented. Give the bandwidth of the digital filter to be used.

Overlapping windows in processing the signals in the morphing project are usually

A 100-point DFT is applied on a 250 Hz cosine waveform that was sampled at 1000 Hz. Give the magnitude of X(k) for k=0,1,..,99.
