## Sanity Check

1. How many genes have p value < 0.05?
1. t15= 385
2. t30= 544
3. t60= 434
4. t90= 231
5. t120= 190
2. What about p < 0.01?
1. t15= 81
2. t30= 108
3. t60= 87
4. t90= 28
5. t120= 34
3. What about p < 0.001?
1. t15= 8
2. t30= 10
3. t60= 6
4. t90= 5
5. t120= 4
4. What about p < 0.0001?
1. t15= 0
2. t30= 1
3. t60= 1
4. t90= 1
5. t120= 0
5. Perform this correction and determine whether and how many of the genes are still significantly changed at p < 0.05 after the Bonferroni correction.
1. t15= 0
2. t30= 0
3. t60= 0
4. t90= 0
5. t120= 0
