WebNov 26, 2024 · The upper bound theorem states that whatever values are taken for l and r will lead to an upper bound. Clearly we wish to find the lowest possible value. From the above geometry, l = rα and r = h 2sinα / 2 ⇒ M = kh2b 4 α sin2α / 2 and so to find the lowest possible value of M, we minimize the function α sin2α / 2 Let Y = α sin2α / 2 WebTo find the confidence interval, start by finding the point estimate: the sample mean. ¯¯x x ¯ = 1.024 Next, find the EBM. Because you are creating a 98% confidence interval, CL = 0.98. You need to find z0.01 having the property that the area under the normal density curve to the right of z0.01 is 0.01 and the area to the left is 0.99.

There are two major types of estimates: point estimate and confidence interval estimate. In the point estimate we try to choose a unique point in the parameter space which can reasonably be considered as the true value of the parameter. On the other hand, instead of unique estimate of the parameter, we are interested in constructing a family of sets that contain the true (unknown) para… WebGiven an upper bound and a lower bound and a sample size, this calculate the point estimate, margin of error.
