z = 1.28, approx.
The value is 0.3055
z = ±0.44
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
Yes. If a score is below the mean, the z score will be negative.
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
z value=0.44
A z score of .5 corresponds to 19% of the data between the mean and z. P( 0 < z < .5) = .19
The value is 0.3055
The mean is 46.
z = ±0.44
There is insufficient information in the question to answer it. To determine Z score, you need raw score, mean, and standard deviation. Please restate the question.
mrs.sung gave a test in her trigonometry class. the scores were normally distributed with a mean of 85 and a standard deviation of 3. what percent would you expect to score between 88 and 91?
A negative Z-Score corresponds to a negative standard deviation, i.e. an observation that is less than the mean, when the standard deviation is normalized so that the standard deviation is zero when the mean is zero.
20 percent
67% as it's +/- one standard deviation from the mean
you have to shoot to score!
