Apoll of 2,097 randomly selected adults showed that 93% of them own cell phones. the technology display below results from a test of the claim that 92% of adults own cell phones. use the normal distribution as an approximation to the binomial distribution, and assume a 0.05 significance level . the test statistic is z=

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
