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.

Step-by-step explanation:
2/4(9) + 8
2/36 +8
using l.c.m
2+36(8)
__________
36
2+288=290/36 =8.1
So 0.1 really means 1/10 of 1 so 10 times of 1/10 is 10/10 or 1
Answer:
35.44 and 35.391...
Step-by-step explanation:
Here are the number to the nearest tenth;
35.45≈35.5
34.42≈34.4
35.391≈35.4
35.44≈35.4
35.041≈35.1
