The Pig 'N' Whistle restaurant in West End is under new management. While under the previous management, 15% of the customers rated their dining experiences as "unsatisfactory". The restaurant's

Using a 5% level of significance, calculate the probability of a Type II error occurring if the actual (population) proportion of unsatisfied customers is 6%. Show all the necessary steps to answer the
question.
