Astudy is conducted to investigate whether a recorded phone call is more effective than a flyer in persuading voters to vote for a particular candidate. the response variable is the proportion of voters planning to vote for the candidate, with p1 and p2 representing the proportions for the two methods (receiving a phone call and receiving a flyer, respectively.) the sample statistic of interest is p^1-p^2. we are testing h0: p1=p2vs ha: p1> p2. a randomization distribution of differences in proportions, p^1-p^2, for this test is shown in the figure below.
(a) four possible sample statistics are given, along with four possible p-values. match the statistics with the p-values.
1. p^1-p^2=0.15 p-value:
0.001
0.310
0.011
0.086

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
