The margin of error for a 95% confidence interval is 0.93.
mean (μ) = 23.4, standard deviation (σ) = 7.6, sample (n) = 254, confidence = 95% = 0.95
α = 1 - C = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
The z score of α/2 is equal to the z score of 0.475 (0.5 - 0.025) which is equal to 1.96.
The margin of error (E) is given by:
