The natural rising and falling of ocean water due to the gravitational pull from the moon has a period of approximately 12 hours. At a certain location, the maximum height of 21 feet occurs at 4:00 a.m. and the minimum height of 5 feet occurs at 10:00 a.m. 1. Find a sine or cosine function that models the ocean water height at time t, measured in hours from midnight. You must show your work and explain how you got all parts of your answer.

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.
