If a normal distribution has mean 34.31 and standard deviation 1.25, then the z-value for this mean is:
A) 27.45
B) 0
C) 34.31
D) 42.89
= Standard deviation
In the current case, x is mean
Therefore , Z = 0
Ans: B) 0
If a normal distribution has mean 34.31 and standard deviation 1.25, then the z-value for this...
A z score of 1.25 represents an observation that is a) 1.25 standard deviation below the mean. b) 0.25 standard deviations above the mean of 1. c) 1.25 standard deviations above the mean. d) both b and c Assume that your class took an exam last week and the mean and standard deviation of the exam were 85 and 5, respectively. Your instructor told you that 30 percent of the students had a score of 90 or above. You would...
