Can you help me with this problem?

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (u, p, o) for the indicated parameter.
A psychologist claims that more than 5.8% of the population suffers from professional problems due to extreme shyness. Use p, the true percentage of the population
that suffers from extreme shyness.
O A. Ho: p=5.8%
H1:p<5.8%
В. Но: р-5.8%
H1:ps5.8%
OC. Ho: p=5.8%
H1:p>5.8%
Sce
D. Ho: p=5.8%
H1:p25.8%

Do one of the following, as appropriate: (a) Find the critical value z12, (b) find the critical value t2, (C) state that neither the normal nor the t distribution applies.
90% confidence interval for u; n= 9; 6 = 4.2; population appears to be very skewed.
O A. z12 =2.365
O B. z/2 =2.896
C. Z/2 =2.306
D. Neither the normal nor thet distribution applies.

Expert Solution
Step 1

In this case, a test is required to see whether more than 5.8% of the population suffers from professional problems. Here, the claim implies that the "greater than" sign should be used as part of the alternative hypothesis H1. Thus, the null and alternative hypothesis can be written as:
