Answer 2

Answer:

z score = 2.24

Step-by-step explanation:

A normally distributed data set is given with a mean of 154 standard deviation 9.8.

If one of the observed value is 176, then we have to calculate the z-score.

z value = $\frac{Score-mean}{standarddeviation}$

z score = $\frac{176-154}{9.8}$

            = $\frac{22}{9.8}$ = 2.24

z score = 2.24
