For Χ2-distribution critical values, use our chi-square distribution calculator

Given α = 0.03, calculate the right-tailed and left-tailed critical value for Z

Calculate right-tailed value:
Since α = 0.03, the area under the curve is 1 - α → 1 - 0.03 = 0.97

Our critical z value is 1.8808
In Microsoft Excel, this function can be written in a cell as =NORMSINV(0.97)

Calculate left-tailed value:
Our critical z-value = -1.8808
In Microsoft Excel, this function can be written in a cell as =NORMSINV(0.03)
