3. You want to determine the effectiveness of a novel cancer therapy, RS7, in treating lung cancer. You cultured lung cancer microtissues in cell culture plates with equal numbers of cells per well. You exposed plate 1 to the novel drug and left plate 2 untreated (control). You analyzed both plates using flow cytometry and propidium iodide to identify live and dead cells. The results below represent the number of viable cells. Using a t-test, determine whether RS7 reduces the viability of lung cancer cells. Plate 1 (RS7): X1 = 65,434 X2 = 70,250 Plate 2 (control): X'1 = 80,760 X'2 = 78,562 X3= 63,962 X'3=81,435 X4= 61,030 X'4 = 75,650 X5= 60,572 X'5 = 77,112

3. You want to determine the effectiveness of a novel cancer therapy, RS7, in treating lung cancer. You
cultured lung cancer microtissues in cell culture plates with equal numbers of cells per well. You
exposed plate 1 to the novel drug and left plate 2 untreated (control). You analyzed both plates using
flow cytometry and propidium iodide to identify live and dead cells. The results below represent the
number of viable cells. Using a t-test, determine whether RS7 reduces the viability of lung cancer cells.
Plate 1 (RS7):
X1 = 65,434
X2 = 70,250
Plate 2 (control):
X'1 = 80,760 X'2 = 78,562
X3= 63,962
X'3=81,435
X4= 61,030
X'4 = 75,650
X5= 60,572
X'5 = 77,112
