In three samples of 50 lines each from Shakespeare's "Romeoand Julliet" (an early play), the following numbers of weak endings wereobserved; 7, 9, 10. In three similar samples from "Cymbeline" (late), thenumber of weak endings were 15, 11, 12. Discuss the suggestion thatShakespeare's prosody, as judged by the number of weak endings, changedwith advancing years.

14. A telephone poll was conducted in a large area to determine if there was a relationship between income level and education level. Random cell phone numbers from the area were dialed and the income and education level of the all the people called was recorded. The surveyed showed that the more education a person has, on average, the higher their income level. Which of the following is truc about the relationship between income level and education level in this area The relationship is questionable because the results are confounded with owning a cell phonc. a. The relationship is questionable because the results are affected by nonresponse. The relationship is questionable because they did not call all oell phone owners The survey had significant results so it seems that education level causes an incrcase in income level. b. c. d.
A college president wanted to know how 10-year-after-graduation salaries for aca- demic majors (English, psychology, math, etc.) compared to salaries for career-oriented majors (business, engineering, computer science, etc.). She matched 84 academic majors at her college with 84 career-oriented majors on the basis of SAT scores and GPA. She found MAcademic = $59,250, MCareer =$61,000, sD = 9,500. Use an alpha of .05 and a two-tailed test to determine if there is a difference in salaries.

A researcher studies the effects of guilt on memory. First, subjects perform a very boring task for one hour. Then each subject is instructed to tell the next subject either (a) that the experiment took one hour and they found it very boring, or (b) that the experiment took one hour and was very interesting. After that, each subject is asked to study a list of words and are tested on memory for the list. 30 subjects are randomly assigned to one of the two conditions. In order to see whether the experimental manipulation has any effect on memory, which would be the proper statistical test? A)a related sample t-test-test   B)an independent sample t-test   C)a z test   D)a one sample t
There are two main fishing spots in a certain video game, a river and a lake. In the river, out of the 57 fish that were caught, 31 of them were trout. In the lake, out of the 64 fish that were caught, 24 of them were trout. Use a significance level of a = 0.02 to test the claim that the proportion of trout in the river is greater than the proportion of trout in the lake. Let the river represent population 1, and the lake represent population 2. a.) State the null and alternative hypothesis using correct symbolic form. Ho: P1 P2 H1: P1 + P2 b.) What is the critical value? (round to two decimal places)

With a view to study whether the working condition in a factory had any influénce on the frequency of accidents, a researcher collected and tabulated the accident data as follows: No. of Accidents Working Condition Total Less More Good 280 80 360 Bad 120 120 240 Total 400 200 600 Using Yule's methodology, calculate the coefficient of association between the number of accidents and the working condition in the factory.

Suppose you are the manager of two beachfront hotels : The Palms and Golden Sands. You'd like to know if there is a difference in guest satisfaction between the two hotels. To investigate this, you conduct a survey and ask guests upon departure if they are likely to return to the hotel in the future. For The Palms, 163 out of 227 guests who were surveyed responded " yes ". For Golden Sands, 154 out of 262 guests responded "yes ". Answer the following questions. Round any numbers in your final answers to 2 decimals. 1) Calculate a 95 % confidence interval for the difference in satisfaction rates between The Palms and Golden Sands (Show work) 2) Use the critical value approach to test, at a 1% significance level, whether or not the guest satisfaction rates are different between the two hotels. What do you conclude ? (In your answer, show the steps involved with testing) 3) What is the p-value of your test in part 2?
We are interested in looking at the effect of a baseball player’s free agent status on their salary. We look at 337 baseball players and categorize them as either having a high salary (above 2 million) or not, and as either being free agents or not. ------------------------------ You also wonder if having a high batting average affects the salary of baseball players. You classify all 370 baseball players as having a high batting average if it is over .300. 1. The given χ2test table gives many test statistics. The row we want to look at is labeled Pearson Chi-Square. Give the test statistic, the degrees of freedom, and the p-value. 2. At a significance level of .05, what can you conclude in the context of this problem?
In a series of studies, Sebastian Deri and his colleagues (2017) asked multiple groups about the number of friend groups they had and how often they attended different social events. They then asked participants how they thought their own numbers compared to other people's: Did participants see themselves as less social, the same as, or more social than others? In the first study, the researchers reported that: "Three hundred four participants from Amazon's Mechanical Turk (150 women; Mage = 37.1; 78% White, 10% Black, and 6% Asian) completed a survey in exchange for modest payment" (p. 860). What do the researchers mean by "Amazon's Mechanical Turk" with respect to their sample of participants? O A. An archival data set that already exists and from which researchers can use data O B. An online tool that researchers can use to recruit people to participate in research in exchange for a small payment O C. An e-book sold by Amazon that includes contact information for possible…
