The pollsters found that found that 89% indicated they were satisfied with their level of care.. The pollsters used this sample to make an inference that approximately 89% of all patients will be satisfied with their level of care. Identify the statistic and parameter in this scenario. O statistic - Sample proportion of patients who are satisfied; parameter - Sample proportion of patients who are satsisfied O statistic - population proportion of patients who will be satisfied. ; parameter - Sample proportion of patients who are satisfied O statistic - Sample proportion of patients who are satisfied ; parameter - population proportion of patients who will be satisfied. O statistic - population proportion of patients who will be satisfied; parameter - population proportion of patients who will be satisfied.The overnight shipping business has skyrocketed in the last ten years. The single greatest predictor of a company's success is customer service. A study was conducted to determine the customer satisfaction levels for one overnight shipping business. In addition to the customer's satisfaction level, the customers were asked how often they used overnight shipping. The results are shown below in the following table: Satisfaction level Frequency of Use High Medium Low TOTAL 5 per month 70 25 5 100 TOTAL 460 220 20 700 A customer is chosen at random. Given that the customer uses the company more than five times per month (>5), what is the probability that the customer expressed high satisfaction with the company?
