Answer:

0.5

Explanation:

Zscore = (x - mean) / standard deviation

Given the data:

X : 462 490 350 294 574

The second observation = 490

The mean and standard deviation of the data could be obtained using a calculator :

Mean = 434

standard deviation = 112

ZSCORE = (490 - 434) / 112

ZSCORE = 56 / 112

ZSCORE = 0.5
