Answer:
Thus, The correct answer is B. 1 - P(z < 2.1)
Step-by-step explanation:
We are given that : P(z < –2.1)
And we need to find an equivalent statement for this.
The given statement needs to find the area under the curve when the z-score is less than -2.1
As the sum is equivalent to 1 , so to find the area under the given value we subtract the positive value of the given z-score from 1.
Hence, The given expression P(z < –2.1) is equal to 1 - P(z < 2.1)
Therefore, The statement equivalent to the given P(z < –2.1) is 1 - P(z < 2.1)
Thus, The correct answer is B. 1 - P(z < 2.1)
The equivalent statement for the z score is P(z < -2.1) = 1 - P(z < 2.1)
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (raw score - mean) / standard deviation
From the normal distribution table:
P(z < -2.1) = 1 - P(z < 2.1)
The equivalent statement for the z score is P(z < -2.1) = 1 - P(z < 2.1)
