I’m confused on this one

It would be b.

It would be first a reflection across A because the points of the triangle are equidistant from the line as they were before just on the other side of the line.

Then it would be a translation because the triangle still holds the same orientation(I don't know if this is the right word) but is moved to a different spot.

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)
