   The correct option is C.

   What do you mean by Z score?

   The relationship between a value and the mean of a group of values is quantified by a Z-score. The Z-score is calculated using standard deviations from the mean. When a data point’s Z-score is 0, it means that it has the same score as the mean.

   How do you find z-score?

   The z-score can be calculated using the formula z = (x -μ ) / σ if you know the mean and standard deviation, where x is your data point, is the mean, and is the standard deviation.

   According to the given information:

   Normally distributed data set with a mean of 154 and a standard deviation of  = 9.8

   if one of the observed values is 176, what is the z score.

   so,

   Z value  = (score –  mean)/standard deviation

   Z value = (176-154)/9.8

                = 2.24

   The z score of the given  statement is  = 2.24
