The value for z is calculated by subtracting the value of the average daily return selected for the test, or 1% in this case, from the observed average of the samples. Next, divide the resulting value by the standard deviation divided by the square root of the number of observed values.

Therefore, the test statistic is:

(0.02 - 0.01) (0.025 50) = 2.83

The investor rejects the null hypothesis since z is greater than 1.96 and concludes that the average daily return is greater than 1%.
