How are key features of a linear function identified and interpreted from a table?

Klio2033 [76]

An increasing linear function results in a graph that slants upward from left to right and has a positive slope. A decreasing linear function results in a graph that slants downward from left to right and has a negative slope. A constant linear function results in a graph that is a horizontal line.

A manufacturer claims that fewer than 6% of its fax machines are defective. In a random sample of 97 such fax machines, 5% are d

Kipish [7]

Answer:

$z=\frac{0.05 -0.06}{\sqrt{\frac{0.06(1-0.06)}{97}}}=-0.415$

Now we can find the p value with the following probability:

$p_v =P(z$

Step-by-step explanation:

Information given

n=97 represent the random sample taken

$\hat p=0.05$ estimated proportion of defective

$p_o=0.06$ is the value to verify

z would represent the statistic

$p_v$ represent the p value

Hypothesis to tests

We want to tet if the true proportion is less than 6%, the system of hypothesis are:

Null hypothesis: $p\geq 0.06$

Alternative hypothesis: $p < 0.06$

The statistic is given by:

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

Replacing the info given we got:

$z=\frac{0.05 -0.06}{\sqrt{\frac{0.06(1-0.06)}{97}}}=-0.415$

Now we can find the p value with the following probability:

$p_v =P(z$

For both of these, we will divide the wanted outcome by the number of possible outcomes. We will end up with a decimal. A decimal multiplied by 100 becomes a percent.

[a] 50%

$\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed}}{\text{Period 2's class}} =\frac{12}{24} =0.5,\:0.5*100=50\%$

[b] 52%

$\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed from Period 3}}{\text{fails from both classes}} =\frac{13}{25} =0.52,$

$\displaystyle 0.52*100=52\%$
