A fair coin should land showing tails with a relative frequency of 50% in a long series of flips. Connor reads that spinning - rather than flipping - a US penny on a flat surface is not fair, and that spinning a penny makes it more likely to land showing tails. She spun her own penny 100 times to test this and the penny landed showing tails in 60% of the spins. Let p represent the proportion of spins that this penny would land showing tails.
What are appropriate hypotheses for Connor's significance test?
A. H_0 : p = 50% H_1 : p > 60%
B. H_0: p = 50% H_1: p > 50%
C. H_0: p = 50% H_1: p < 50%
D. H_0 : p = 60% H_1 : p < 60%

True of false: the chancellor of a university has commissioned a team to collect data on students' gpas and the amount of time they spend bar hopping every week (measured in minutes). he wants to know if imposing much tougher regulations on all campus bars to make it more difficult for students to spend time in any campus bar will have a significant impact on general students' gpas. his team should use a t test on the slope of the population regression.
