Answer:

Mean of M = 0.794

Standard Error = 0.013875

Step-by-step explanation:

Given that :

Sample size, n = 64

Mean percentage accuracy, μ = 0.794

Standard deviation, σ = 0.1110

Since the distribution of scores is normal ;

Sample mean, m ~ μ

Hence, m ~ 0.794

The sample sta dard deviation of standard error ~ σ/sqrt(n)

Standard Error = 0.1110 / sqrt(64)

Standard Error = 0.1110 / 8

Standard Error = 0.013875
