A pharmaceutical company is developing a treatment for blindness caused by diabetic retinopathy. Thus, 5 patients with advanced retinopathy were selected. For each patient, their left eye was treated and their right eye was left untreated. The time to blindness (in months) was recorded for both eyes and all patients as follows:

Patient	1	2	3	4	5
Treated Eye	51.1	49.0	49.6	47.7	50.5
Untreated Eye	28.7	31.2	35.6	36.2	40.5

Calculate a 95% confidence interval to assess the difference in time to blindness due to treatment.

A pharmaceutical company is developing 3 new drugs that bind to the same receptor as nicotine and acetylcholine (ACh). They perform a series of experiments to determine the concentration-response relationship for each new drug. All drugs showed a sigmoidal concentration-response curve when plotted on a semi-logarithmic scale. Their data shows that Drug A has an EC50 of 100 nM and a maximum effect of 99%. Drug B has an EC50 of 15 nM and a maximum effect of 95%. Drug...
