Betreff: st: testing normalitt of data

can I use the t-test for independent samples when the skewness and kurtosis
of data are as follow
skewness: -1.232 & the std. error of skewness is .616/ .044 and the std.
error of skewness is .427
kurtosis: 2.195 & the std. error of kurtosis is 1.191/ -.505 and the std.
error of kurtosis is .833
I really need help and guidance to make decisions about using the t0test
