Aprimatologist believes that rhesus monkeys possess curiosity. she reasons that, if this is true, then they should prefer novel stimulation to repetitive stimulation. an experiment is conducted in which 10 rhesus monkeys are randomly selected from the university colony and taught to press two bars. pressing bar 1 always produces the same sound, whereas bar 2 produces anovel sound each time it is pressed. after learning to press the bars, the monkeys are tested for 15 minutes, during which they have free access to both bars. the number of presses on each bar during the 15 minutes is recorded. the resulting data are as follows (show all work) a. what is the alternative hypothesis? in this case, assume a nondirectional hypothesis is appropriate because there is insufficient empirical basis to warrant a directional hypothesis. b. what is the null hypothesis? c. using α = 0.052 tail, what is your conclusion? d. what error might you be making by your conclusion in part c? subjectbar 1bar 2 12040 21825 32438 41427 5531 62621 71532 82938 91525 10918

1.3.25 question suppose 40​% of all voters voted for a particular candidate. to simulate exit polls regarding whether or not voters voted for this​ candidate, five random samples of size 1010 and five random samples of size 10001000 have been generated using technology using a population proportion of 0.400.40​, with the accompanying results. complete parts a through c below. click the icon to view the simulation results. a. observe how the sample proportions of successes vary around 0.400.40. simulation compared to sample prop simulation compared to sample prop 1 ▾ 6 ▾ greater than 0.40 less than 0.40 equal to 0.40 2 ▾ less than 0.40 greater than 0.40 equal to 0.40 7 ▾ greater than 0.40 less than 0.40 equal to 0.40 3 ▾ greater than 0.40 less than 0.40 equal to 0.40 8 ▾ equal to 0.40 greater than 0.40 less than 0.40 4 ▾ greater than 0.40 equal to 0.40 less than 0.40 9 ▾ less than 0.40 greater than 0.40 equal to 0.40 5 ▾ equal to 0.40 less than 0.40 greater than 0.40 10 ▾ equal to 0.40 greater than 0.40 less than 0.40 click to select your answer(s) and then click check answer. 2 parts remaining clear all check answer
