Considering the desired result of the hypothesis test, we the closest mean time to 1.5 hours, hence the correct option is:
C. 1.6 hrs
<h3>What should be the mean?</h3>
The closer the mean is to the sample mean, the less likely we are to reject the null hypothesis.
In this problem, the sample mean is of 1.5 hours, hence, the closest value, considering the absolute value of the difference, is of 1.6 hours, hence option C is correct.

Answer:
Subtract 23 from both sides
Step-by-step explanation:
This is how algebra works, to get a variable by itself you have to do the opposite to both sides. Hope this helped.
X=5 and y=5 √2
In a 45 45 90 triangle
Both legs are of the same value and the hypotenuse is any leg times √2
The answer is C because spending no time on video games gets you at least 9 for a range, and spending as much time as she wants to means the number will increase meaning "greater than"
