The velocity of an object moving along a line is given by v = 4t +2 ft/s on the interval 1sts5. a. Divide the interval [1, 5] into subintervals, [1, 2], [2, 3], [3, 4], and [4, 5]. On each subinterval, assume the object moves at a constant velocity equal to the value of v evaluated at the midpoint of the subinterval and use these approximations to estimate the displacement of the object on [1, 5]. (See part (a) of the figure.) b. Repeat part (a) for n = 8 subintervals (see part (b) of the figure). Click the icon to view the figures. a. For n= 4 subintervals, the approximate displacement of the object is (Simplify your answer.) ft.

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.
