Step-by-step explanation:
If Z is following a standard normal distribution, then P(Z>0) would be 0.5. Standard normal distributions are symmetrical with a mean of 0, so half of the distribution will be above 0 (i.e., 0.5).
Answer:
C) 26
Step-by-step explanation:
41 , 35,30 , X , Y ,15
Number of data's = 6. So, median will be the average of . 3 and 4th term
Median =
30 + X = 25*2
30 + X = 50
X = 50 - 30
X = 20
Mode is 15
So, Y = 15
41,35,30,20,15,15
