WebSep 5, 2024 · x 2 = (100/100) + (100/50) = 1 + 2 = 3 . 5. Choose a significance level. Now that we know our experiment's degrees of freedom and our chi square value, there's just … WebWe know that the probability P(X > 75) is equal to 1 – P(X ≤ 75), so we can use a table to find P(X ≤ 75). This result is equal to P(Z ≤ 0.5) (where Z is the standardized random variable). The table states that P(Z ≤ 0.5) = 0.6915 Now we can calculate P(X > 75). P(X > 75) = 1 – P(X ≤ 75) = 1 – P(Z ≤ 0.5) = 1 – 0.6915 = 0.3085
