Math Problem Statement
keith does a survey at his school all the pupils take in the survey.he draws this two way table
girls- right handed is 188 girls left handed is 32 and the boys right handed is 203 and the left handed is 37
Solution
Let's summarize the data from the survey into a two-way table:
Right-handed | Left-handed | Total | |
---|---|---|---|
Girls | 188 | 32 | 220 |
Boys | 203 | 37 | 240 |
Total | 391 | 69 | 460 |
Here’s the breakdown:
- 188 girls are right-handed, and 32 girls are left-handed, making a total of 220 girls.
- 203 boys are right-handed, and 37 boys are left-handed, making a total of 240 boys.
- In total, 391 pupils are right-handed, and 69 pupils are left-handed, which gives a total of 460 pupils surveyed.
Would you like more details or have any specific questions about the table?
Here are 5 follow-up questions:
- What proportion of girls are left-handed?
- What percentage of the total students are boys?
- How many more boys than girls are left-handed?
- What is the probability that a randomly chosen student is right-handed?
- What is the ratio of right-handed boys to right-handed girls?
Tip: When creating two-way tables, always include row and column totals to make data interpretation easier.
