The given bivariate data is(1,6),(3,2),and(2,4).
Calculation:
First determine xiyi,xiandyi.
xi first coordinates of the ordered pairs.
yi second coordinates of the ordered pairs.
xiyi=16+32+24=20
xi=1+3+2=6
yi=6+2+4=12
For covariance sxyusing forμ sxy=xiyixiyinn1.
Where n = number of ordered pairs.
n=3
sxy=20612331
=2072331
=2242
=42=2
Hence sxy=2.

One hundred adults and children were randomly selected and asked whether they spoke more than one language fluently. The data were recorded in a two-way table. Maria and Brennan each used the data to make the tables of joint relative frequencies shown below, but their results are slightly different. The difference is shaded. Can you tell by looking at the tables which of them made an error? Explain. Maria's table YesNo Children0.150.25 Adults0.10.6 Brennan’s table YesNo Children0.150.25 Adults0.10.5

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 $ lim{n}a{2n}an<12 then an converges, while if lim{n}a{2n+1}an>12 then an $ diverges. Let an=nlnn(lnn)n. Show that a2nan0 as n

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?
