Answer:
Step-by-step explanation:
I don’t know sorryyyy
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:
Any line with a slope (m) of 2/5
Step-by-step explanation:
It is easy to find the slope of a perpendicular line when one of the lines is given. All you have to do is flip the fraction (If it is a whole number, set under 1.), and change the sign (negative to positive, and vice versa).
In this case the perpendicular slope of (-5/2) is 2/5.
