A pharmaceutical company is testing a new drug. For the study, the company enrolled 200 people who had previously been diagnosed with a specific condition. Half took the study drug and half took a placebo. Throughout the study, the participants were routinely asked to fill out a 50-question survey. After six months, the participants on the study drug showed positive improvements in their answers. What is the best way the company could improve this study to prove more thoroughly that its medications work

The quantitative data must be collected and test statistics performed.

Step-by-step explanation:

The quantitative data must be collected by performong different test such blood test etc. Then the improvement in the medications work can be found out by applying different test statistics such as difference tests , etc.

The quantititave data will show how much there has been improvement by using  drugs and placebo.

The test statistic will provide a basis for the quick decision without waiting for 6 months.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
