. In terms of the mean and standard deviation:
- What does it mean to say that a particular value of x has a standard score of +1.5?
- What does it mean to say that a particular value of x has a z-score of -2.6?
Please show all work.

    If a value of x has a standard score of 1.5, this means that x is 1.5 standard deviations above the mean.

    The mean divides a distribution in half. Half the values are above the mean and half are below the mean.

    I'll let you try the second question on your own.

    I hope this helps.
