Answer:
0.3019
Step-by-step explanation:
Null hypothesis: the average age of a groom is now 26.2 years.
Alternative hypothesis: the average age of a groom is not 26.2 years.
We have a sample of 16 so we will use a t-test
Where t score = (x-u)/(sd/√n)
Where x = 26.6, u=26.2, sd= 5.3 and n=16
t score = (26.6-26.2) / (5.3/√16)
t = 0.4/(5.3/4)
t = 0.4/1.325
t = 0.3019
