Most adults would not erase all of their personal information online if they could. A software firm survey of 480 randomly selec
Westkost [7]

Answer:

-7.90

Step-by-step explanation:

Let's write the null hypothesis (H0) and alternative hypothesis (Ha) from the claim statement

P = population proportion of adults who would erase all of their personal information online if they could

H_{0}:P=0.5

H1 P< 0.5

Let's write the given information:

n = sample size = 480

sample proportion = \hat p = 0.35

formula of z test statistic for one sample proportion test is as follows:

Z=\frac{\hat p-P}{\sqrt{\frac{P\times(1-P)}{n}}}

plug the above values in the above formula we get

Z =\frac{0.35-0.5}{\sqrt{\frac{0.35(1-0.5)}{480}}}=Z=-7.85584

So that the test statistic value is -7.90 (Rounded up to two decimal places)

suppose the circumference of a crop circle is 150.7968 hectometers (hm) what's the radius of the circle? (usett=3.1416)​
gulaghasi [49]

Answer:

The radius of the circle is 24\ hm

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

In this problem we have

C=150.7968\ hm

\pi=3.1416

substitute and solve for r

150.7968=2(3.1416)r

r=150.7968/(2(3.1416))=24\ hm

A diagonal shortcut across a rectangular lot is 130 feet long. The lot is 50 feet long. What is the other dimension of the lot
ryzh [129]
We use the pithagorean formula: x^2 = 130^2 - 50^2 = 16900 -2500 = 14400;
then, x = \sqrt{14400} = 120 feet has the other dimension of the lot.
