4. Find missing number in frequency table. Then find the relative frequency that if you play sports in the winter, it will be baseball. Round to nearest tenth percent.
Frequency table:
- Basketball: 15
- Football: 20
- Soccer: 12
- Baseball: ?
To find the missing number in the frequency table, we need to determine the total number of students surveyed. Adding up the frequencies given:
15 (Basketball) + 20 (Football) + 12 (Soccer) + x (Baseball) = Total number of students surveyed
Since x represents the missing frequency for baseball, we will replace x with the missing number in the frequency table to find the total number of students surveyed.
15 + 20 + 12 + x = Total number of students surveyed
47 + x = Total number of students surveyed
Next, we need to find the relative frequency for playing baseball in the winter. Given that the total number of students surveyed is 47, we can calculate the relative frequency for baseball.
Relative Frequency of Baseball = (Frequency of Baseball / Total number of students surveyed) x 100%
Relative Frequency of Baseball = (x / 47) x 100%
To find the relative frequency that if you play sports in the winter, it will be baseball, we need to know the value of x.
Once we determine the missing frequency for baseball, we can calculate the relative frequency to find the percentage.
