In a survey of 155

155 seniorexecutives,

51% said that the most common job interview mistake is to have little or no knowledge of the company. Use a 0.05

significance level to test the claim that in the population of all seniorexecutives,

40% say that the most common job interview mistake is to have little or no knowledge of the company. Identify the nullhypothesis, alternativehypothesis, teststatistic, P-value, conclusion about the nullhypothesis, and final conclusion that addresses the original claim. Use theP-value method. Use the normal distribution as an approximation of the binomial distribution.
