The mean of a distribution of 1000 individuals' blood pressure is 85. If this number were translated into a Z score it would be equal to +1 standard deviations. True or False?

I know to calculate a Z score the formula is Z= (X-sub-i minus the mean)/ standard deviation.
the mean= 85, but I'm not sure what the other values should be. It seems like there is not enough information given to solve the problem

    Is Z = +1 the same as the mean? That should give you the answer.
