Sample information: 24 out of 1000 people who were surveyed had type 2 diabetes. Use the above sample information and construct

notka56 [123]

Solution :

The sample proportion $(\hat p)=\frac{24}{1000}$

= 0.024

90% confidence interval

The standard deviation = $\sqrt{\frac{\hat p(1-\hat p)}{n}$

= $\sqrt{\frac{0.024(1-0.024)}{1000}$

= 0.00484

z = 1.645 for 90% CI

Upper band = 0.024 + (0.00484 x 1.645 ) = 0.03196

Lower band = 0.024 - (0.00484 x 1.645 ) = 0.01603

Therefore, the 90% CI is (0.016, 0.032)

99% confidence interval

z = 2.576 for 99% CI

Upper band = 0.024 + (2.576 x 0.00484 ) = 0.0365

Lower band = 0.024 - (2.576 x 0.00484 ) = -0.0115

Therefore, the 99% CI is (0.0115, 0.0365)

Solve for x by factorising. 3x²+4x= 4

Ivan

Answer:

Step-by-step explanation:

3x^2+4x-4=0 (we move 4 to the other side to factor)

(3x-2)(x+2)

^think of 2 numbers that when you multiply it will be -4 and when you multiply one of it to 3x and add to the other it will be 4x.

Recheck:

-2(2)= -4 (correct)

-2x+6x=4x (correct)
