If mean equals 18.6 standard deviation equals 4 what is the z score?
The z score, for a value y, is (y - 18.6)/4
How do you calculate a raw score from a z score?
z = (x - μ) / σ is the formula where x is the raw score and z is the z-score. μ and σ are the mean and standard deviations and must be known numbers. Multiply both sides by σ zσ = x-μ Add μ to both sides μ + zσ = x x = μ + zσ You calculate the raw score x , given the z-score, μ and σ by using the above formula.
What is the z score for a given raw score?
Let your raw score be x and M the mean and S the standard deviation. The Z score for your specific x is Z=(x-M)/S So say your score is 80 (out of 100) and the mean is 70 and the standard deviation is 10. Then the z score for your 80 is: (80-70)/10=1 If on the other hand you got a 60, then the z score would be -1.
What is the z score of x equals 124 The mean is 100 and the standard deviation is 8?
It is (124 - 100)/8 = 24/8 = 3
What is the Z score formula for statistics?
z=x-mean / sd
If mean equals 18.6 standard deviation equals 4 what is the z score?
The z score, for a value y, is (y - 18.6)/4
X varies directly with y and inversely with z x equals 0.12 when y equals 12 and z equals 2 Find x when y equals 1200 and z equals 1?
x = 24
If log5 x equals z then x is?
logbase5 of x =z x=5^z
If x equals y and y equals z then you can deduce that x equals z is the law of?
transitive property!

X varies directly with y and z x equals 400 when y equals 8 and z equals 10 Find x when y equals 10 and z equals 12?
x = 5.y.z so 5.10.12 = 600
What would the Z score be if Z equals 0 and Z equals -1.41?
1.41

X varies directly with y and inversely with z x equals 125 when y equals 5 and z equals 4 Find x when y equals 4 and z equals 5?
Given x=k1y and x=k2/z x=125 ,y=5 then k1=25 x=125 , z=4 then k2=125(4)=500 If y=4 ,z=5 then x=25y = 100
X varies directly with y and inversely with z x equals 0.25 y equals 10 and z equals 20 find x when y is 20 and z is 10?
