In the figure below, if the z -test value is 1.43 for a test of the difference between two large sample
means, then the null hypothesis should not be rejected.

Since the z-test value is less than the critical value for a significance level of α = 0.05 (which is approximately 1.96 for a two-tailed test), we fail to reject the null hypothesis. Therefore, the statement in the question is true. The z-test value of 1.43 is below the critical value for a two-tailed test with a significance level of α = 0.05. Therefore, we fail to reject the null hypothesis.
