Suppose a new cancer treatment was given to a sample of 300 patients. the treatment was successful for 210 of the patients. assume that these patients are representative of the population for whom the treatment would be successful, including a margin error.

a. 70% ± 5.3%

Step-by-step explanation:

The proportion is:

p = 210 / 300 = 0.7

The margin of error is:

ME = z √(p (1 − p) / n)

where z is the critical value, p is the proportion, and n is the sample size.

For a 95% confidence interval, z ≈ 2.

ME = 2 √(0.7 (1 − 0.7) / 300)

ME = 0.053

So the proportion is 70% ± 5.3%.

a. 70% ± 5.3%

Step-by-step explanation:

Supposing a new cancer treatment was given to a sample of 300 patients and the treatment was successful for 210 of the patients. These patients are representative of the population for whom the treatment would be successful, including a margin error. Therefore, the answer is 70% ± 5.3%.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
