please answer the above question :)

2. 10 marks. Business owners in a certain company have been trying to improve customer satisfaction for their product this year. The customer satisfaction level last year was 65%, and their goal this year is to increase it to 80%. Clients from four districts of Sydney were surveyed this month and asked if they were satisfied with the product. The results were the following. Number of people satisfied in: Abbotsford, 40; Greendale, 9; Northwood, 4; and West- mead, 12. Number of people unsatisfied in: Abbotsford, 18; Greendale, 1; Northwood, 3; and West- mead, 8. Owner Johnson claims that based on these numbers, their improvement goal has been achieved. Owner Smith disagrees, saying the satisfaction has increased, but doesn't appear to be at 80% yet.
