Spotify is a digital music, podcast, and video service that allows individuals to access millions of songs and other material from creators all over the world. In August, 2019, a sample of 50 songs from Spotify was analyzed using a special algorithm in order to measure song popularity. A higher popularity measure is better and reflects how popular a song is relative to other songs on Spotify. The distribution of popularity measures for the songs in this sample is presented below. What should you conclude based on an examination of this distribution? 14 12 Frequency 2- 75 05 90 Popularity One song has a popularity measure of 70. O There are no obvious outliers in this distribution. 32% of the songs in this sample have popularity measures that are 90 or higher. O We should describe the shape of this distribution as being skewed to the right. O This type of graphical display is known as a bar graph.Question 5 1 pts Corgis are a particular breed of dog. The boxplot below displays the weights (in pounds) of a sample of corgis, and the five-number summary for this sample of data is as follows: Minimum = 20 pounds, Q1 = 22 pounds, Median = 24 pounds, Q3 = 29 pounds, and Maximum = 34 pounds. Based on this information, which one of the following statements is correct? 20 22 24 30 32 34 Weight O There must be at least one corgi in the sample that weighs exactly 24 pounds. O If the maximum corgi weight was changed from 34 pounds to 50 pounds, the median would change. O The percentage of corgis in the sample that weigh less than 22 pounds is the same as the percentage of corgis in the sample that weigh more than 29 pounds. O The percentage of corgis in the sample that weigh less than 24 pounds is smaller than the percentage of corgis in the sample that weigh more than 24 pounds. O There is exactly one outlier in the sample.Question 9 1 pts In the spring of 2022, a random sample of 1000 adults were surveyed about who should be inducted into the Rock and Roll Hall of Fame in 2022. The survey results are presented in the table below. The most appropriate graphical display to use to summarize this data would be a Artist Percentage Dolly Parton 33% Lionel Richie 31% Carly Simon 26% Pat Benatar 26% Dionne Warwick 25% O pie chart O bar graph O histogram O boxplot O line graphD Question 10 1 pts The two boxplots below display final exam scores, measured in points, for all students in two different sections of the same course. The five-number summaries for each of these sections are presented below the boxplots. Which one of the following statements is a correct interpretation of how these two sections compare with each other? Section A Section B 0 10 20 30 40 50 60 70 80 90 100 1 10 120130 140 150 Exam Scores Section Minimum Q1 Median Q1 Maximum A 20 40 80 120 150 B 56 80 100 133 O When compared to Section B, Section A has a larger percentage of students who scored above 80 points on the final exam. O When compared to Section A, Section B has a larger IQR. O More information is needed in order to determine what the 50th percentile is in each of the sections. O More students must have been enrolled in Section A compared to Section B. O None of the above answers are correct interpretations of the boxplots and summary statistics.D Question 7 1 pts In Dr. Agarwal's calculus course, most students earned high scores on the final exam, and only a very small number of students earned low scores. When summarizing the final exam scores, Dr. Agarwal computed two measures of center: 69.5 points and 82.5 points. One of these measures is the mean and one is the median. Which measure must be the mean? O The mean is 69.5 points because the distribution of exam scores would be skewed to the left. O The mean is 69.5 points because the distribution of exam scores would be skewed to the right. O The mean is 82.5 points because the distribution of exam scores would be skewed to the left The mean is 82.5 points because the distribution of exam scores would be skewed to the right. O It is impossible to answer this question without more informationStep by Step Solution
