Question

scientists give two different treatments to people who have the flu and determine if their health improves. the results for the experiment are in the two - way table.

what percentage of people receiving treatment 1 had improved health?

what percentage of people receiving treatment 2 had improved health?

Explanation:

Step1: Calculate total number for treatment 1

Total for treatment 1 is \(23 + 17=40\)

Step2: Calculate percentage for treatment 1

Percentage of people with improved health in treatment 1 is \(\frac{23}{40}\times100\)
\(=\frac{23\times100}{40}= 57.5\%\)

Step3: Calculate total number for treatment 2

Total for treatment 2 is \(25+35 = 60\)

Step4: Calculate percentage for treatment 2

Percentage of people with improved health in treatment 2 is \(\frac{25}{60}\times100\)
\(=\frac{25\times100}{60}\approx41.67\%\)

Answer:

a. \(57.5\%\)
b. \(41.67\%\)
