The following table shows scores on the first quiz (maximum score 10 points) for eighth-grade students inan introductory level French course. The instructor grouped the students in the course as follows:- Group 1: Never studied foreign language before but have good English skills- Group 2: Never studied foreign language before and have poor English skills- Group 3: Studied at least one other foreign languageFrench scores on the quizGroup 1Group 2 Grouр 341951085Mean6.03.08.0Std.

Name one important reason for this.(Hint: For given sample means, how do the results of the test depend on the sample sizes?)c) Was this an experimental study, or an observational study? Explain how a lurking variable could beresponsible for Group 3 having a larger mean than the others. (Thus, even if the P-value were small, it isinappropriate to assume that having studied at least one foreign language causes one to perform betteron this quiz.)

Suppose we want to compare the GPA for students in at least three different social classes (Upper, Middle, Working). We obtain GPA records for a randomly selected set of 30 students, ten from each social class group. What test should you use and why?
The following test scores are for two classes that took the same test. (The highest possible score on the test was 60.) Class 1 (24 scores): 37, 45, 52, 55, 11, 55, 44, 55, 35, 25, 52, 42, 35, 21, 42, 52, 41, 40, 34, 51, 41, 41, 41, 41 Class 2 (25 scores): 50, 40, 40, 23, 40, 50, 31, 31, 40, 31, 31, 31, 53, 33, 33, 35, 55, 24, 39, 40, 41, 59, 41, 39, 46 Form a back-to-back stem and leaf plot with one stem.

A researcher wanted to know whether perception of a person’s height depends on his/her perceived status. A random sample of army inductees was selected and equally divided between four groups.

Select the correct sentence in the passage. Which sentence best supports the idea that artificial and human translators are comparable? A Computer Can Now Translate Languages as Well as a Human by Vanessa Bates Ramirez (excerpt) In other words, it’s finally happened: computers are smarter than people. In a contest that tested the new software against human translators, it came close to matching the fluency of humans for some languages. People fluent in two languages scored the new system between 64 and 87 percent better than the previous one. Google is already using the new system for Chinese to English translation and plans to completely replace its existing translation technique with the GMNT.
