A survey of eating habits showed that approximately 5​% of people in a certain city are vegans. Vegans do not eat​ meat, poultry,​ fish, seafood,​ eggs, or milk. A restaurant in the city expects 350 people on opening​ night, and the chef is deciding on the menu. Treat the patrons as a simple random sample from the city and the surrounding​ area, which has a population of about​ 600,000. If 18 vegan meals are​ available, what is the approximate probability that there will not be enough vegan meals—that ​is, the probability that 19 or more vegans will come to the​ restaurant? Assume the vegans are independent and there are no families of vegans.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
