Thread: Null Hypothesis Question - Need Help!

Need some guidance on solving this null hypothesis problem.

Test the claim at 1% significance level that graduates from University X and University Y experience the same salary increase after graduation.

Univesity X
Mean $8,000
Standard Deviation: $1,000

University Y
Mean $7,000
Standard Deviation: $1,000

Should (could) this be done in Excel through a t test: two sample assuming equal variances?

Do you have a sample size?

Sorry, yes. University x = 100, University Y = 100
