Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter.

Answer: The confidence interval would be (0.2928,0.3672).

Step-by-step explanation:

Since we have given that

Total number of vehicles = 432

Number of SUVs sold = 142

So, it becomes,

$\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33$

At 90% confidence interval,

z = 1.645

So, the confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)$

Hence, the confidence interval would be (0.2928,0.3672).

a floor is 450 ft by 90 ft. A scale drawing of the floor on grid paper uses a scale of 1 unit:5 feet. what are the dimensions of

Minchanka [31]

450/5= 90 units

90/5= 18 units

All you need to do is divide the real dimensions by the scale dimensions, and turn that answer to units. Notice: It said 1 unit: 5 feet

The scale drawing was 90 to 18 units.

I hope this helps!

What should be added to 8 to make the sum 0
