Question: A recent issue of the AARP Bulletin reported that the average weekly pay for a woman with a high school school degree is $520 (AARP Bulletin, January-February, 2010). Suppose you would like to determine if the average weekly pay for all working women is significantly greater than that for women with a high school degree. Data providing the weekly pay for a sample of 50 working women are available in the file named WeeklyPay. These data are consistent with the findings reported in the AARP article.

Express the limit limn→∞ i=1Σn xi ln(1 + xi2)?x, where ?x = 6-2/n and xi = 2 + i?x, as a definite integral on the interval [2, 6]
Let V and W be vector spaces and T: V --> W be linear. Suppose that T is one-to-one and that S is a subset of V. Prove that S is linearly independent if and only if T(S) is linearly independent.
Compute the work required to compress a spring 2 more cm when it is already compressed 3 cm, assuming that the spring constant is k = 150 kg/s2.
Find the general solution of the differential equation - Please show all work
The idea is that you exercise your muscles by stretching the spring from its natural length, which is 34 cm. If a 140 Newton force is required to keep the spring stretched to a length of 51 cm, how much work is required to stretch it from 52 cm to..
