A random sample of students at a very large university was asked which social-networking site they used most often during a typical week. Their responses are shown in the table below.
Assuming that gender and preferred networking site are independent, which of the following is the expected count for female and LinkedIn?
Beavers and beetles Do beavers benefit beetles? Researchers laid out 23 circular plots, every four meters in diameter, at random in an area where beavers were cutting down cottonwood trees. In each plot, they counted the number of stumps from trees cut by beavers and the number of clusters of beetle larvae. Ecologists think that the new sprouts from stumps are more tender than other cottonwood growth so beetles prefer them. If so, more stumps should produce more beetle larvae.
Minitab output for a regression analysis on these data is shown below. Construct and interpret a 99% confidence interval for the slope of the population regression line. Assume that the conditions for performing inference are met.
The slope of the population regression line describes
(a) the exact increase in the selling price of an individual unit when its appraised value increases by
(b) the average increase in the appraised value in a population of units when the selling price increases by \)51000.
(c) the average increase in selling price in a population of units when the appraised value increases by \( 1000.
(d) the average selling price in a population of units when a unit's appraised value is 0.
(e) the average increase in appraised value in a sample of 16 units when the selling price increases by \) 1000.
Two six-sided dice are rolled and the sum of the faces showing is recorded after each roll. Let the number of rolls required until a sum greater than is obtained. If trials are conducted, which of the following is most likely to be part of the probability distribution of ?
Determining tree biomass It is easy to measure the 鈥渄iameter at breast height鈥� of a tree. It鈥檚 hard to measure the total 鈥渁boveground biomass鈥� of a tree, because to do this you must cut and weigh the tree. The biomass is important for studies of ecology, so ecologists commonly estimate it using a power model. Combining data on trees in tropical rain forests gives this relationship between biomass measured in kilograms and diameter x measured in centimeters:
