Determine whether the samples are independent or dependent.To test the effectiveness of a drug, cholesterol levels are measured in 80 men and80 women after the treatment.Choose the correct answer below.O A. The samples are independent because there is a natural pairing between the two samples.O B. The samples are dependent because there is not a natural pairing between the two samples.O C. The samples are independent because there is not a natural pairing between the two samples.O D. The samples are dependent because there is a natural pairing between the two samples.

Given a data set, how do you know whether to calculate o or s? Choose the correct answer below. O A. When given a data set, one would have to determine if it represented the population or if it was a sample taken from the population. If the data are a population, then o is calculated. If the data are a sample, then s is calculated. O B. If the given data set contains a large number of entries, then s is calculated. If the data set contains a small number of entries, then o is calculated. O C. If the given data set contains a large number of entries, then o is calculated. If the data set contains a small number of entries, then s is calculated. O D. When given a data set, one would have to determine if it represented the population or if it was a sample taken from the population. If the data are a population, then s is calculated. If the data are a sample, then o is calculated.

Steven Schmidt (1994) conducted a series of experiments examining the effects of humor on memory. In one study, participants were given a mix of humorous and nonhumorous sentences and significantly more humorous sentences were recalled. However, Schmidt argued that the humorous sentences were not necessarily easier to remember, they were simply preferred when participants had a choice between the two types of sentence. To test this argument, he switched to an independent-measures design in which one group got a set of exclusively humorous sentences and another group got a set of exclusively nonhumorous sentences. The following data are similar to the results from the independent- measures study. Use = .05 (two-tail) for your criteria.
A random sample of 7 oak trees from two forests was gathered. The results are shown below. Height of Trees (feet) Forest A Forest B 70 92 78 82 84 66 83 76 78 72 88 79 77 85 Based on the samples, which statement best compares the height of the oak trees in each forest? O The oak trees in Forest A are generally taller and have less variabillity than the oak trees in Forest B. The oak trees in Forest A are generally shorter and have less variabillity than the oak trees in Forest B. O The oak trees in Forest A are generally taller and have more variabillity than the oak trees in Forest B. The oak trees in Forest A are generally shorter and have more variabillity than the oak trees in Forest B.
