Answer:
C
Step-by-step explanation:
The temperature must not be greater than 15 which means 15 is the maximum. It's not saying it can't reach 15, it's saying it can't go past it. 
So it wouldn't be t < 15. It would be t is less than or equal to 15

Answer:
you<u> accept </u>the alternative hypothesis
Step-by-step explanation:
The null and alternative hypothesis can be computed as follows:

The sample proportion 


The test statistics can be computed as:


Z = -2.5
The P-value = 2( Z< -2.5)
From the tables;
The P-value = 2 (0.0062)
The P-value = 0.0124
The significance level = 0.01
Since the P-value is > significance level; we fail to reject the null hypothesis.
Conclusion: we accept the alternative hypothesis
