Answer:
Step-by-step explanation:
The common factor is the largest number that goes into both of those numbers evenly. We do this by finding the prime factorization of each:
25: 5,5
35: 5,7
The common number to both is 5, so 5 is the common factor of both the numerator and denominator.
Answer:
Step-by-step explanation:
Put hypotheses as:

(Two tailed test at 4%)
Since population std deviation is given we can do Z test.

Test statistic t = mean diff/se = 
p value=0.075
Since p >0.04 our alpha, we accept null hypothesis.
At alphaequals0.04, we cannot reject the company's claim
