Web2 dagen geleden · 7. Determine the critical value for a 95% level of confidence (p<0.05). If you are using the 95% confidence level, for a 2-tailed test you need a z below -1.96 or above 1.96 before you say the difference is significant. For a 1-tailed test, you need a z greater than 1.65. The critical value of z for this test will therefore be 1.65. 8. Web30 nov. 2024 · Using eigenvalues to determine critical points with sympy.
