Slope = (y2-y1)/(x2-x1)
= (2/3 - 2) / (1 -1/2)
=-4/3 / 1/2
=-4/3 * 2
= -8/3

Claim: Most adults would erase all of their personal information online if they could.A software firm survey of 453 randomly sel

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 n = 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, p = 0.50.

A z-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.

Please help me with this equation, add process too. Thanks

$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

Let's solve ~ ☂

$\qquad \sf \dashrightarrow \: - 0.6(m + 1) = 3$

$\qquad \sf \dashrightarrow \: - (m + 1) = 3 \div 0.6$

$\qquad \sf \dashrightarrow \: - (m + 1) = 5$

$\qquad \sf \dashrightarrow \: - m - 1= 5$

$\qquad \sf \dashrightarrow \: - m = 5 + 1$

$\qquad \sf \dashrightarrow \: - m = 6$

$\qquad \sf \dashrightarrow \: m = - 6$

I hope it helps ~
