A jar contains 4 blue buttons, 5 green buttons, and 1 white button. A student chooses a button and records it's color and then places the button back in the jar. The student repeats this process 50 times. the table shows the results.
blue=26
green=21
white=3
Was each color chosen more or fewer times than expected
For each color, we can calculate the expected frequency based on the total number of trials and the proportion of that color in the jar.
Expected frequencies:
Blue: (4/10) * 50 = 20
Green: (5/10) * 50 = 25
White: (1/10) * 50 = 5
Comparing the expected frequencies to the actual frequencies in the table:
Blue: 26 (more than expected)
Green: 21 (fewer than expected)
White: 3 (fewer than expected)
