Question: A population has a mean of 200 and a standard deviation of 50. Suppose a simple random sample of size 100 is selected and I' is used to estimate p.
a. What is the probability that the sample mean will be within . ± 5 of the population mean?
b. What is the probability that the sample mean wiII be within ± 10 of the population me an?
Suppose f(x) is an invertible differentiable function and the graph of f passes through the points (4, 2) and (2, 4). The slope of the tangent line to the graph of f at x = 2 is 5/8
Problem: A light is located over the center of circular table of diameter d = 8 feet (see figure). Find the height h of the light source such that the illumination I at the perimeter of the table is maximum when:
A graphical representation of a linear program is shown in the attachment. The shaded area represents the feasible region, and the dashed line in the middle is the slope of the objective function.
Question 1: When comparing two population means with an unknown standard deviation you use a t test and you use N-2 degrees of freedom.
