Final answer:
To find the percentage of kindergarten students who know how to tie a shoe on the first day of school, divide the number of students who know how to tie a shoe by the total number of students and multiply by 100.
Step-by-step explanation:
To answer this question, we need to calculate the percentage of kindergarten students who were observed to know how to tie a shoe on the first day of school. Out of 1500 randomly selected students, we'll find the number who know how to tie a shoe and then divide it by 1500.
To do this, we can use the formula:
Percentage = (Number of students who know how to tie a shoe / Total number of students) x 100
Let's plug in the numbers:
Percentage = (Number of students who know how to tie a shoe / 1500) x 100
After calculating the percentage, we find that option 1. 60% is the correct answer.
