Hypothesis Testing Help

I just need help starting this problem. I'm taking the class online and I'm having trouble.

In 2015, Netflix subscribers spent an average of 1.5 hours per day streaming content. To determine if there is an increase in viewing, suppose a new survey was conducted of subscribers. Of the 354 people who responded to the survey, an average of 1.6 hours per day were spent streaming content with a standard deviation of 0.4 hours. Test the claim that there has been an increase in Netflix viewing. Use a significance level of 0.01. Use the 8 step hypothesis testing procedure.

Would P= 1.5 and p>1.5 be the claim?
I was told it was wrong but I cant figure it out

Treat it as if you are testing whether 1.5 hrs/day falls within the 99% confidence region of 1.6 hr/day, with 0.4 std.

Thanks for the help, Romsek. I'm still stuck on this problem about how to get it going. Could you clarify more for me or give an example?
