It is believed that 11% of all Americans are left-handed. In a random sample of 100 students from a particular college with 1012
tia_tia [17]

Answer:

Step-by-step explanation:

We can calculate this confidence interval using the population proportion calculation. To do this we must find p' and q'

Where p' = 14/100= 0.14 (no of left handed sample promotion)

q' = 1-p' = 1-0.14= 0.86

Since the requested confidence level is CL = 0.98, then α = 1 – CL = 1 – 0.98 = 0.02/2= 0.01, z (0.01) = 2.326

Using p' - z alpha √(p'q'/n) for the lower interval - 0.14-2.326√(0.14*0.86/100)

= -2.186√0.00325

= -2.186*0.057

= 12.46%

Using p' + z alpha √(p'q'/n)

0.14+2.326√(0.14*0.86/100)

= 0.466*0.057

= 26.5%

Thus we estimate with 98% confidence that between 12% and 27% of all Americans are left handed.

What is the median of the following numbers? 4, 5, 5, 2, 1, 3, 4, 5, 4, 4, 4, 7
Katen [24]

Answer:

4

Step-by-step explanation:

Rewrite is order going from least to greatest.

1, 2, 3, 4, 4, 4, 4, 4, 5, 5, 5, 7

Find the middle number.

Because there are an even amount of numbers you have to take the two middle numbers which are 4 and 4 add them which gives you 8 and then divide that by 2( because you added two numbers.)

Therefore the answer is 4

How do you solve this problem?
motikmotik

The arcs AB, BC, AC all equal to the third of the perimeter since equilateral triangle divides them like this.

So we need to find a perimeter but we are only given the area.

Let's review,

A=\pi r^2 \\P=2\pi r

That means that from area we area able to calculate radius.

A=\pi r^2\Longrightarrow r=\sqrt{\dfrac{A}{\pi}}

Insert the numbers,

r=\sqrt{\dfrac{36\pi}{\pi}}=6

Then use the perimeter formula to calculate perimeter since radius is known,

P=2\pi\cdot6=12\pi

Now divide perimeter by 3 to get length of AB arc.

AB=\dfrac{12\pi}{3}=\boxed{4\pi}

Hope this helps.
