Question
A psychologist is interested in constructing a 99% confidence interval for the proportion of people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain. 56 of the 705 randomly selected people who were surveyed agreed with this theory.
a. With 99% confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain is betweenand .
b. If many groups of 705 randomly selected people are surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain and about percent will not contain the true population proportion.

All stimulus persons gave the same verbal speech. After observing this person, the participants had to rate the stimulus person’s level of intelligence on a scale of 1-10. The participants were separated by gender and their ratings were analyzed separately. How many possible interaction effects might the researcher find? Group of answer choices 3 0 1 2arrow_forward
- A study by a reputable research group captured multitasking activities of adults who use different devices while watching TV. The study reported that 320 of 442 (72%) smartphone users sampled, 192 of 350 (55%) computer users sampled, and 139 of 260 (53%)tablet users sampled used their device to check social media unrelated to the video content while watching TV. Complete parts (a) through (c) below. a. Is there evidence of a significant difference among the smartphone, computer, and tablet users with respect to the proportion who use their device to check social media unrelated to the video content while watching TV?

The other member is told (also in private) that his or her partner has rated that person at the low end of the trustworthiness scale. Each person is then asked to estimate, in turn, the trustworthiness of his or her partner, yielding the following results.

They randomly assigned volunteers into one of three groups. The people in the first group were asked to taste a snack that was described as a new health bar containing high levels of protein, vitamins, and fiber. The people in the second group were asked to taste the same snack but were told it was a tasty chocolate bar with a raspberry center. After tasting the snack, participants were asked to rate their hunger level on a scale from 1 (not at all hungry) to 7 (very hungry). The people in the third group were asked to rate their hunger but were not given a snack. The data in the table are consistent with summary quantities given in the paper (although the sample sizes in the actual study were larger).

After ten minutes, the subjects were asked to look at a poster with pictures of 20 common objects for five minutes. After waiting ten minutes, the subjects were asked to list as many of the objects as they could recall. For the subjects that took the drug, 75% were able to list at least half of the objects. For the subjects that took the placebo, 70% were able to list at least half of the objects. Check that the conditions are met for a hypothesis test to compare the population proportion of subjects that took the drug that could list at least half of the objects to the proportion that took the placebo that could. Select the correct answer below: All of the conditions are met. The samples are not random samples of the populations. O The samples are not independent.

They recruited 24 participants separated into four age groups. The groups differ according to the age of subjects. In group one, all participants are 30 years old. Group 2, 40 years old. Group 3, 50 years old. And group 4, 60 years old. Assume that the participants are all in good health and that the groups are matched on other important variables such as years of education, IQ, gender, motivation, and so on. Each participant is shown a series of nonsense syllables ( a meaningless combination of three letters such as Daf or FUM ) at a rate of one syllable every four seconds. The series is shown twice, after which participants are asked to write down as many of the syllables as they can remember. Below is number of syllables remembered by each participant. 30 years old 14 13 15 17 12 10 40 years old 12 15 16 11 12 18 50 years old 17 14 14 9 13 15 60 years old 13 10 7 8 6 9 what is the alternative and null…arrow_forward
