A large company claims that 68% of their employees feel appreciated by their supervisor. During the company's evaluation process, an independent company surveys a random sample of 158 employees and asks them if they feel appreciated by their supervisor. Based on some complaints, they assume that less than 68% of employees feel appreciated.
Test the claim at the 5% significance level. Use the fact that out of the 158 surveyed employees 99 said that they feel appreciated by their supervisor.
Are the conditions satisfied to carry out the hypothesis test?
