= 13.25
s1 = 4.5036
 = 16.25
s2 = 2.1373
Option - D)
The test statistic is
P-value = P(T < -2.71)
= 0.0034
Since the P-value is less than the significance level (0.0034 < 0.1), so we should reject the null hypothesis.
Option - C) Reject the null hypothesis. There is sufficient evidence to support the claim that Archbishap have lower mean longetivity.
