Using the SAS data set SASHELP.HEART, write all of the SAS code needed to produce a three-way frequency table for SEX, STATUS and WEIGHT_STATUS. Write the code so the tables are produced that have the values of SEX in the rows, WEIGHT_STATUS in the columns and separate tables across pages for values of STATUS.

Using the SAS data set SASHELP.HEART, write all the SAS code needed to create 2 SAS data setscontaining the data for each of the 2 frequency tables requested in the previous problem.  DO NOT include missing values for this question.  DO USE the option to suppress output to the Output Window (or Results Viewer).

Using the same data as in question 4, provide a description of what the percentage highlighted in yellow represents.   Your description should be similar in form to the questions in the previous item. 

Define and describe, in your own words, sampling rate. 

The polarity convention for electrophysiology states that when G1 is more negative than G2, the pen will:

Mg2+ helps the enzyme DNA polymerase  to bind to it’s substrate. This inorganic mineral could be described as a “___________” .    [other examples include iron & zinc]

White light consisting of wavelengths ranging from 400nm to 700 nm is incident upon a diffraction grating having 600 lines/mm. The first order spectrum extends over a range of angles on a screen. Next, the grating is removed and replaced with one having 900 lines/mm. Which of the following statements is correct about the range of angles comprising the first order spectrum?

Two glass panes each 1.0 cm thick are separated by a thin layer of oil with a thickness of 1.0 cm. The index of refraction of the oil is 1.5. Light with a wavelength of 530 nm in a vacuum travels from point A to point B in 0.14 ns. What is the index of refraction for the glass?
