Answer:
The statement that cushion A is twice as popular as cushion B cannot be verified
Step-by-step explanation:
From the question we are told that:
Sample size n=38
Type a size A 
Type a size B
Generally the probability of choosing cushion A P(a) is mathematically given by


Generally the equation for A to be twice as popular as B is mathematically given by

Therefore Hypothesis

Generally the equation normal approx of p value is mathematically given by



Therefore from distribution table


Therefore there is no sufficient evidence to disagree with the Null hypothesis 
Therefore the statement that cushion A is twice as popular as cushion B cannot be verified
we know that
1 hour is--------> 60 minutes
1 minute is---------> 60 sec
so
10 hour =10*60=600 minutes
39 sec=39/60=0.65 min
10 h 39 sec=600+0.65=600.65 min
therefore
<u>the answer is</u>
600.65 minutes
Taxes you have to pay extra because of taxes
3(6)+8=26
I think 26 is the answer
