Answer: option c
Step-by-step explanation:
margin of error = critical value × s/√n
Where s = sample standard deviation = 0.58, n = 53
The critical value = 1.96 ( this is the critical value for a two test test corresponding to a level of significance of 5%)
By substituting the parameters, we have that
Margin of error = 1.96×0.58/√53
Margin of error = 1.96 × 0.0796
Margin of error = 0.156 ~ 0.16
