Find the following standard normal probability: p(-1.23 szs +1.23) oa..7814 b. 8907 o c..1093 d. 2186
in the formula used to convert "real-world" data values into z numbers, the standard deviation of the data is never considered. o true o false

a) 0.7814

b) False

Step-by-step explanation:

To find : The p-value of z , where

Hence, the standard normal probability

In the formula used to convert "real-world" data values into z numbers, the standard deviation of the data is considered.

The formula to calculate the z score is .

If sample size (n) is given then , the

Hence, the statement is false.

answer: a
