If the Z-Score corresponds to the standard deviation, then the distribution is "normal", or Gaussian.

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 mean is 46.

z score = (test score - mean score)/SD z score = (87-81.1)/11.06z score = 5.9/11.06z score = .533You can use a z-score chart to calculate the probability from there.

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.

The mean is 46.

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.
