2. In volleyball statistics, a block is recorded when a player deflects the ball hit fres opposing team. Additionally, scorekeepers often keep track of the average number blocks a player records in a game. Here is part of a table that records the number os blocks and blocks per game for each player in a women’s volleyball tournament.A scatter plot that goes with the table follows. blocks blocks per game 13 1.18 1 5 0.17 0.42 7 0.64 020 2 201 1.5 208.0 201 1 0.5 7.5 15 22.5 30 a. What should be the label on the horizontal axis of the scatter plot? b. What should be the label on the vertical axis of the scatter plot? c. Using the scatter plot, predict the number of blocks for a player that averages 1.7 blocks per game.
1. The number library books read in one semester by a group of 30 second graders is given in the table at the right. Create a reasonable frequency table for this data set with exactly 5 classes.
