Answer

Answer:

Placebo Luck potion Row total
Blocked the goal 0.57 0.43 1.00
Did not block the goal 0.62 0.38 1.00

Explanation:

Step1: Calculate row - relative frequency for 'Blocked the goal' and 'Placebo'

For the row 'Blocked the goal', the total number of trials in this row is (30 + 23=53). The row - relative frequency for 'Blocked the goal' and 'Placebo' is (\frac{30}{53}\approx0.57).

Step2: Calculate row - relative frequency for 'Blocked the goal' and 'Luck potion'

The row - relative frequency for 'Blocked the goal' and 'Luck potion' is (\frac{23}{53}\approx0.43).

Step3: Calculate row - relative frequency for 'Did not block the goal' and 'Placebo'

For the row 'Did not block the goal', the total number of trials in this row is (8 + 5 = 13). The row - relative frequency for 'Did not block the goal' and 'Placebo' is (\frac{8}{13}\approx0.62).

Step4: Calculate row - relative frequency for 'Did not block the goal' and 'Luck potion'

The row - relative frequency for 'Did not block the goal' and 'Luck potion' is (\frac{5}{13}\approx0.38).
