Test 1 Practice Test #2Peanuts is a syndicated daily and Sunday American comic strip written and illustrated by Charles M. Schulz,which ran from October 2, 1950, to February 13, 2000, continuing in reruns afterward. The strip is the mostpopular and influential in the history of the comic strip, with 17,897 strips published in all, making it "arguablythe longest story ever told by one human being". At its peak, Peanuts ran in over 2,600 newspapers, with areadership of 355 million in 75 countries, and was translated into 21 languages. It helped to cement the four-panel gag strip as the standard in the United States, and together with its merchandise earned Schulz more than$1 billion. Reprints of the strip are still syndicated and run in almost every U.S. newspaper. Peanuts achievedconsiderable success with its television specials, several of which, including A Charlie Brown Christmas and It'sthe Great Pumpkin, Charlie Brown, won or were nominated for Emmy Awards. The holiday specials remainpopular and are currently broadcast on ABC in the United States during the corresponding seasons. The Peanutsfranchise met acclaim in theatre, with the stage musical You're a Good Man, Charlie Brown being a successfuland often-performed production. Peanuts has been described as “the most shining example of the Americansuccess story in the comic strip field”; this is ironic, given its theme is “the great American unsuccess story.” Themain character, Charlie Brown, is meek, nervous, and lacks self-confidence. He is unable to fly a kite, win abaseball game, or kick a football. - Wikipedia1. Of interest is to determine the proportion of all current VCU students who have ever watched a Peanuts special ontelevision. Based on this information, what is the population of interest? 2. Based on the information in question 1, what is the parameter of interest? _____ 3. A sample of 500 current VCU students was selected, and each student was asked whether or not they haveever watched a Peanuts special on television. In this sample 385 students, or 77%, indicated that they havewatched a Peanuts special on television. In this scenario, is 77% an example of a parameter or a statistic?(A) Parameter (B) Statistic_____ 4. To select the sample described in question 3 the following was done. On the Blackboard sites of the tenSTAT 210 sections a poll question was set up that read “Have you ever watched a Peanuts special ontelevision?” 500 of the 1289 enrolled students responded to the poll by clicking on either Yes or No. Whattype of sampling procedure is this an example of?(A) Volunteer response sampling (B) Simple random sampling (C) Haphazard sampling(D) Multistage random sampling (E) Stratified random sampling _____ 5. The 385 students who responded that they have watched at least one Peanuts special on television werethen asked how many Peanuts specials they had watched. In the box they were asked to enter a wholenumber (1, 2, 3, 4, etc). The “number of Peanuts specials that a student has watched” is what type ofcharacteristic?(A) Categorical variable (B) Discrete quantitative variable (C) Continuous quantitative variable (D) Constant_____ 6. The 385 students who responded that they have watched at least one Peanuts special on television werealso asked where they were when they first remember watching a Peanuts special on television. Possibleanswers were: at home, at grandparents home, at a friend’s home, at school, at a place of worship, or other.The “place where a student first watched a Peanuts special on television” is what type ofcharacteristic?(A) Categorical variable (B) Discrete quantitative variable (C) Continuous quantitative variable (D) Constant_____ 7. Suppose in the sample of 500 current VCU students all are undergraduate students. Hence no graduatestudents, medical students, or students in any other professional program were selected. If the viewershipand opinions of undergraduate students regarding Peanuts specials on television is different from that ofthe other student classification groups, what type of bias could this cause?(A) Selection bias (B) Response bias (C) Nonresponse bias (D) Confounding biasOne of the classic Peanuts storylines has Lucy holding a football, while Charlie Brown runs up and attempts to kick theball. On each occasion, at the last second Lucy lifts the ball, so Charlie Brown misses the ball and falls on his back (seethe cartoon below). Of interest is to determine the percentage of all 193,415 football players who have attempted to kicka field goal or extra point in a game and who have missed the ball. 8. Based on the information above, what is the population of interest? 9. Based on the information above question 8, what is the parameter of interest?_____ 10. Research finds only 128 out of 193,415 football players who have attempted to kick a ball in a game haveactually completely missed the ball while kicking. In this scenario, is 128 an example of a parameter or astatistic?(A) Parameter (B) Statistic_____ 11. The “percentage of all football players who have attempted to kick a field goal or extra point in agame and who have missed the ball” is what type of characteristic?(A) Categorical variable (B) Discrete quantitative variable (C) Continuous quantitative variable (D) Constant_____ 12. Of interest is to determine the mean number of times that all players who have kicked a ball in a gamehave actually kicked the ball. This mean cannot be determined because each person who has ever kicked aball in a game cannot be contacted. Therefore a sample of 200 kickers was selected, as follows. Kickerswere divided into four groups by the most advanced level of kicking they had ever done: professional,college, high school, or recreational. Based on the number in each group, the following numbers of kickerswere randomly selected from each group: professional kickers – 5, college kickers – 36, high schoolkickers – 114, recreational kickers – 45. What type of sampling procedure is this an example of?(A) Volunteer response sampling (B) Simple random sampling (C) Haphazard sampling(D) Multistage random sampling (E) Stratified random sampling _____ 13. Consider the sampling situation described in question 12. Of the 41 professional and college kickers, noneof them stated that they had ever missed the ball while attempting to
