The valence of a song is measured from 0 to 10 and detects the musical positiveness conveyed in the song. Tracks with high valence sound more positive (e.g. happy, ch with low valence sound more negative (e.g. sad, depressed, angry). The valence was computed for 42,000 songs on Spotify in the genres of Techno, Techhouse, Trance, Trap, Psytrance, DnB, Hardstyle, Underground Rap, Trap Metal, Emo The table below shows the number of songs with a given valence measurement. Valence 1.5 2.5 4.4 5.3 6.3 6.7 7.7 8.7 9.7 Number of songs 3557 3175 2388 2078 1579 1438 1023 651 245 Source: Kaggle (a) Based on a scatter plot of the data in the table, why is a linear model appropriate?

The first Batman movie was made over 50 years ago in 1966. Över the years, Batman has been played on screen by a number of actors and even by a Lego figure in the Lego Batman movies. In the original comic books, Batman was 188 centimeters tall (about 6'2") and weighed 95 kilograms (about 210 pounds). The article "50 Years of Batman on Film: How Has His Physique Changed?"t included the heights and weights of all of the onscreen Batmen in the table below.
