Hypothesis testing for difference between two population means

Two independent samples were taken from two populations with the following results:

Sample 1	Sample 2
Sample size = 48	Sample size = 39
Mean = 15	Mean = 11
Population standard deviation = 1.8	Population standard deviation = 2.9

For the hypothesis test:
H0 : μ1 - μ2 ≤ 1
H0 : μ1 - μ2 > 1

a. What is the standard error of the difference between the means?

b. What is the value of the test statistic?
