If you need to find a $t^*$ multiplier for a confidence level that's not on our table, you'll need to use some software. You could use a command like the following:

from scipy.stats import t
print(t.ppf(0.92,10))
# Out: 1.517897992387647

Keep in mind that this will depend on the degrees of freedom, as well as the confidence level. Also, that command yields a one sided area and corresponds to a picture that looks like so:

You probably want a two sided computation for a confidence interval and need to make the appropriate change.

If you don't have Python with SciPy handy, you can always do it online like so:
