The U.S. Census Bureau compiles census data on educational attainment of Americans. From the document Current Population Reports, we obtained the 2000 distribution of educational attainment for U.S. adults 25 years old and older. Here is that distribution.
[Table]
A random sample of 500 U.S. adults (25 years old and older) taken this year gave the following frequency distribution.
[Table]
Decide, at the 5% significance level, whether this year’s distribution of educational attainment differs from the 2000 distribution.

1. Determine the observed frequencies and the chi-square subtotals:
2. Add all chi-square subtotals:
x2=2.674
Determine the critical value using table VII with df=c1=61=5.
x20.05=11.070
If the test statistic x2 is more than the critical value, then reject the null hypothesis:
2.674<11.070 Do not reject H0

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.

B. G. Cosmos, a scientist, believes that the probability is 25 that aliens from an advanced civilization on Planet X are trying to communicate with us by sending high-frequency signals to Earth. By using sophisticated equipment, Cosmos hopes to pick up these signals. The manufacturer of the equipment, Trekee, Inc., claims that if aliens are indeed sending signals, the probability that the equipment will detect them is 35. However, if aliens are not sending signals, the probability that the equipment will seem to detect such signals is 110. If the equipment detects signals, what is the probability that aliens are actually sending them?

The following advanced exercise use a generalized ratio test to determine convergence of some series that arise in particular applications, including the ratio and root test, are not powerful enough to determine their convergence. The test states that if $ limna2nan<1/2 then an converges, while if limna2n+1an>1/2 then an  diverges. Let an=nlnn(lnn)n. Show that a2nan0 as n
