Question

question number 2. (10.00 points) given the following sampling distribution: what is p(x > -14)? 0.84 0.85 0.87 0.81 0.86 none of the above

Explanation:

Step1: Recall probability formula for P(X > - 14)

P(X > - 14)=1 - P(X ≤ - 14)

Step2: Find P(X ≤ - 14)

P(X=-17)=\frac{7}{100}=0.07 and P(X = - 14)=\frac{9}{100}=0.09. So P(X ≤ - 14)=P(X=-17)+P(X = - 14)=0.07 + 0.09=0.16

Step3: Calculate P(X > - 14)

P(X > - 14)=1 - 0.16 = 0.84

Answer:

0.84
