Can you help me with these incorrect answers?

1) Calculate the estimate for the standard error of difference between two independent means fors₁²=0.061,s₂²=0.088,n₁=8, andn₂=9. (Give your answer correct to four decimal places.) I had 0.1922

2) Find the98%confidence interval for the difference between two means based on this information about two samples. Assume independent samples from normal populations. (Use conservative degrees of freedom.) (Give your answers correct to two decimal places.)

Sample	Number	Mean	Std. Dev.
1	26	30	24
2	16	26	33

Lower limit:-19.02 (says it is wrong)

Upper limit:-27.02 (says it is wrong
