Observe that point $(3,3)$ can only be obtained via function A: $\frac{1}{3}3^2=3$ .

In all other cases it fails,

$\frac{1}{9}3^2\neq3$

$3\cdot3^2\neq3$

$(\frac{1}{3}\cdot3)^2\neq3$

Hope this helps :)

Hey there!

<h3>"Expanded form" is basically, setting it up in a addition form to give you that result</h3>

$4 = 400,000 \\ 0 = 0 \\ 3 = 3,000 \\ 8 = 800 \\ 9 = 90 \\ 2 =2 \\ \\ \\ \\ Answer: 400,000 + 0 + 3,000 + 800 + 90 + 2$

Good luck on your assignment and enjoy your day!

Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come f

AlladinOne [14]

Answer:

$z=\frac{0.64 -0.5}{\sqrt{\frac{0.5(1-0.5)}{75}}}=2.43$

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

$p_v =P(z>2.43)=0.0075 \approx 0.008$

Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportion for this case is higher than 0.5

Step-by-step explanation:

Data given and notation

n=75 represent the random sample taken

$\hat p=0.64$ estimated proportion of interest

$p_o=0.5$ is the value that we want to test

$\alpha=0.05$ represent the significance level

Confidence=95% or 0.95

z would represent the statistic

$p_v$ represent the p value

System of hypothesis

We want to verify if the true proportion is higher than 0.5:

Null hypothesis: $p =0.5$

Alternative hypothesis: $p > 0.5$

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:

$z=\frac{0.64 -0.5}{\sqrt{\frac{0.5(1-0.5)}{75}}}=2.43$

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

$p_v =P(z>2.43)=0.0075 \approx 0.008$

Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportion for this case is higher than 0.5
