4. The results of testing a new drug on 1,000 people with a certain disease found that 510 of them improved when they used the d
Shalnov [3]

Answer:

It would not be reasonable to say that  more than half of the people with this disease would  improve if they used the new drug

Step-by-step explanation:

Data provided in the question:

Sample size,  n = 1000

Number of people improved when they used the drug = 510

Thus,

Probability that Number of people improved when they used the drug

= 510 ÷ 1000

= 0.510

Now,

margin of error, E = 2\times\sqrt{\frac{p(1-p)}{n}}

= 2\times\sqrt{\frac{0.510(1-0.510)}{1000}}

= 0.032 = 3.2%

Therefore,

Portion of 0.510 is likely to lie in the 3.2% of the actual value of population

And,

The lower portion can be as small as p - E

= 0.510 - 0.032

= 0.478 i.e 47.8% of the sample

Hence,

It would not be reasonable to say that  more than half of the people with this disease would  improve if they used the new drug
