Answer:
We don't have sufficient evidence to support the claim
Step-by-step explanation:
Null hypothesis:
![H_0: p = 0.276](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D%200.276)
Alternate hypothesis:
![H_1: p < 0.276](https://tex.z-dn.net/?f=H_1%3A%20p%20%3C%200.276)
The P-value is 0.3064
0.3064 probability of finding a sample proportion lower than the one found.
The p-value is higher than the significance level of 0.05, which means that there is no sufficient evidence to support the claim.
