Answer:

<u><em>Relative frequencies</em></u>

Growth mind set fixed mind set Total

Attendance

every practice 0.7 0.3 1

missed at-least

one practice 0.1344 0.8656 1

<u>Step-by-step explanation:</u>

Growth mind set fixed mind set total

Attendance

every practice 28 12 40

missed at-least

one practice 9 58 67

<u><em>Relative frequencies</em></u>

Growth mind set fixed mind set Total

Attendance

every practice $\frac{28}{40} = 0.7$ $\frac{12}{40} = 0.3$ 1

missed at-least

one practice $\frac{9}{67} = 0.1344$ $\frac{58}{67} = 0.8656$ 1

<u><em>Final answer</em></u>:-

<u><em>Relative frequencies</em></u>

Growth mind set fixed mind set Total

Attendance
