Assuming we're using the t-distribution (in practice we shouldn't have to, since the sample size is high!) we have:

Standard error = sd / sqrt(n)

= 0.0511/sqrt(46)

= 0.007534

The confidence interval will be given by:

mean +/- t_crit * Standard error

= 0.307 +/- 2.412*0.007534

= 0.289 to 0.325
