A group of scientists are investigating species diversity on an uninhabited chain of islands. The scientists design a research study in which they visit a large island in
the chain that is located 5 miles from the nearest island. The research island is also
far from the main shipping routes and 20 miles from the mainland. They mark off a
one-hectare study plot of forested land and catalog the number of distinct species
found within the plot. To validate their findings, the scientists want to choose a
second island in the chain to visit and replicate their study.

Asmall internet mail-order company keeps track of the number of orders it fills per day for many years and determines that the distribution of the variable "orders filled per day" is right-skewed and has the following five-number summary: minimum = 20 q1 = 32 median = 46 q3 = 63 maximum = 80 suppose we take random samples of size 40 from this distribution and calculate the range for each of our samples. (i cant put in the graph, but its approximately normal with center between 56 and 57, with a range of 53 to 60). a) there are two dots on the graph at 53. explain what these values represent. b) is the sample range an unbiased estimator of the population? use the dotplot above to justify your answer.

Which statement describes absolute and apparent brightness? absolute brightness and apparent brightness are identical ways to describe the brightness of a star. absolute brightness and apparent brightness change with the distance from the star to the observer. absolute brightness depends on the distance from the star to the observer, whereas apparent brightness is always the same. absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer.

Why does pacholke say that it shouldn’t make you happy that “as a prison system, as a nation, and as a society, we've become very good” at containing and controlling the people who have fallen through all of the other societal safety nets? what do you feel that he is insinuating by this statement? explain.
