To test the effectiveness of a new drug, a researcher gives one group of patients the new drug and another group a placebo. Results are shown below:
Medication
Effective
Not effective
Active Drug
151
25
Placebo
12
33
Is the proportion of patients who showed effectiveness of active drug significantly higher than the
proportion of patients who showed effectiveness in placebo group? Use alpha=0.05.
The approximate z test statistic for this test can be:​

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
