An industrial designer wants to determine the average time it takes for an adult to assemble a toy. 24 people were randomly chosen to assemble the toy and the time taken (in minutes) were as follows:

17, 13, 18, 19, 17, 21, 29, 22, 16, 28, 21, 15 26, 23, 24, 20, 8, 17, 17, 21, 32, 18, 25, 22

Using interval estimate to infer the population mean with a 95% confidence level

${\int}_{0}^{2\pi}\frac{1}{{\mathrm{sin}}^{4}x+{\mathrm{cos}}^{4}x}$

1) I've tried multiplying by ${\mathrm{sec}}^{4}x$ and doing u substitution, but It used crazy amounts of upper level maths

2) I've tried double/half angle identities to simplify down to $\frac{1}{1-\frac{1}{2}{\mathrm{sin}}^{2}2x}$

3) I've mixed strategies and came up with $\frac{4\mathrm{cos}2x}{4\mathrm{cos}2x-\mathrm{cos}3x\mathrm{cos}x}$

Classify each of the studies as either descriptive or inferential. Explain your answers. In an article titled “Teaching and Assessing Information Literacy in a Geography Program” (Journal of Geography, Vol. 104, No. 1, pp. 17-23), Dr. M. Kimsey and S. Lynn Cameron reported results from an on-line assessment instrument given to senior geography students at one institution of higher learning. The results for level of performance of 22 senior geography majors in 2003 and 29 senior geography majors in 2004 are presented in the following table.
