Asked Feb 15, 2019

Identify the following distribution as binomial, geometric or neither.

A headache remedy is said to be 80% effective in curing headaches caused by simple nervous tension. An investigator tests this remedy on 100 randomly selected patients suffering from nervous tension and counts how many have had headache relief after taking the drug.

a) Binomial

b) Geometric

c) Neither

Step 1

In this question we have given some data based on that we have to find that which distribution is being followed by the given data. In this an investigator has tested a remedy on 100 patients and he got that remedy is 80% effectivce.

Step 2

Based on given information, we can say that given data follows binomial distribution.

Conditions to be fulfilled for binomial distribution:

- Each trial must be independent of each other.
- Probability of success must be the same for all events.
- Each trial must represent either success or failure...
