Anit [1.1K]

Answer:

The value of the test statistic is 4.26.

Step-by-step explanation:

In this case a hypothesis test is performed to determine whether most adults would erase all of their personal information online if they could.

A random sample of <em>n</em> = 453 adults were selected and it was found that 60% of them would erase all of their personal information online if they could.

Assume that the population proportion is, <em>p</em> = 0.50.

A <em>z</em>-test for single proportion would to used to perform the test.

Compute the value of the test statistic as follows:

z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}

  =\frac{0.60-0.50}{\sqrt{\frac{0.50(1-0.50)}{453}}}\\\\=\frac{0.10}{0.0235}\\\\=4.25532\\\\\approx 4.26

Thus, the value of the test statistic is 4.26.

How to solve 2x-4(x+3)= x-3
Murrr4er [49]

Answer: x=-3

Step-by-step explanation:

2x-4(x+3)=x-3

2x-4x-12=x-3

-2x-12=x-3.    add 12 to both sides

-2x=x+9.        subtract x from both sides

-3x=9.            Divide both sides by -3

x=-3
