If my result is significant, do I reject my null hypothesis?: The t-value is 2.76273. The p-value is .006739. The result is significant at p < .05 Also, do I reject null for this information below too?: The t-value is 21.65739. The p-value is < .00001 (p-value ≈ 0). The result is significant at p < .05.

Question
If my result is significant, do I reject my null hypothesis?:
The t-value is 2.76273. The p-value is .006739. The result is significant at p < .05
Also, do I reject null for this information below too?:
The t-value is 21.65739. The p-value is < .00001 (p-value ≈ 0). The result is significant at p < .05.
Expert Solution
Step 1
a)
From the given information,
t-value = 2.76273
p-value = 0.006739
The significance level = 0.05
Step 2
Decision rule:
Conclusion:
Since the p-value is less than significance level (0.05). So, reject the null hypothesis at 5% level of significance.
Reject the null hypothesis.
