The sum of two number is 91. The smaller number is thirteen less than the large number. Find both numbers.

Feliz [49]

What you would do is make the equation:
91=X+(X-13)
Then, you would solve for X and once you find X, you would subtract 13 from it.
The answers should be 52 and 39.

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)
