Answer:
5
Step-by-step explanation:
405=9x9xj
rearrange
j=5
2^1 1^2
3^1 or 1^3
4^1 1^4
I'm not sure which.
The equation of the line graphed below would be D. I can find two points that are easily distinguishable on this graph. (1, 5) and (0, 0). I found the slope by subtracting 0 from 5 giving me -5. Next, I subtracted 0 and 1 giving me -1. This gives me a fraction of -5/-1 which equals to 5.
The answer is A because when y = 3^x is graphed the equation stays steady until -2 on the x plane then rapidly shoots up.
Using the z-distribution, it is found that since the test statistic is greater than the critical value for the right-tailed test, this result shows that Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time.
<h3>What are the hypothesis?</h3>
- At the null hypothesis, it is tested if Zwerg cannot correctly follow this type of direction by an experimenter more than 50% of the time, that is:

- At the alternative hypothesis, it is tested if Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time, that is:

<h3>Test statistic</h3>
The <em>test statistic</em> is given by:

In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
For this problem, the parameters are:

The value of the <em>test statistic</em> is:



Considering a <u>right-tailed test</u>, as we are testing if the proportion is greater than a value, with a <u>significance level of 0.05</u>, the critical value for the z-distribution is
.
Since the test statistic is greater than the critical value for the right-tailed test, this result shows that Zwerg can correctly follow this type of direction by an experimenter more than 50% of the time.
