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 =
=
= 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
Answer:
The length of hypotenuse is cm
Step-by-step explanation:
Let's length of hypotenuse is x
Since, a 12 cm altitude to the hypotenuse of a right triangle divides the hypotenuse into segments with ratio 3:2
so,
First part of hypotenuse length is
Second part of hypotenuse length is
now, we can draw triangle
We can see that
triangles ABD and ABC are similar
so, the ratio of their sides must be equal
now, we can solve for x
So,
The length of hypotenuse is cm
