Answer:
c) H0 : p = 5.8%
H1 : p > 5.8%
Step-by-step explanation:
At the null hypothesis, we test that the percentage is equal to a certain value. At the alternate hypothesis, we have a test about this percentage, if it is more, less, or different from the tested value.
A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness
At the null hypothesis, we test if the percentage is 5.8%

At the alternate hypothesis, we test if this percentage is more than 5.8%. So

This means that the correct answer is given by option c.
To perform the following operation, make sure to do the division parts separately and place them back together in the final answer.
10/2 and x^5/x^2
5 and using the exponential laws of division X ^m/X^n = X ^ m-n
The second part evaluates to X^3.
Putting the terms together we get the final answer, which is 5x^3.
