Answer:
1. 4 gal= 16 qt.
2. 6 qt= 12 pt.
3. 11 pt= 176 fl oz.
4. 18 c= 144 fl oz.
5. 48 qt= 12 gal.
6. 17 gal= 136 pt.
7. 19 qt= 76 c.
8. 256 c= 16 gal.
9. 12 gal= 96 pt.
10. 28 c= 14 pt.
11. 17 c= 136 fl oz.
12. 128 fl oz= 16 c.
13. 8 gal= 32 qt.
14. 20 qt= 640 fl oz.
15. 4 qt= 8 pt.
16. 18 qt= 72 c.

Differential<span> wheeled robot is a mobile robot whose movement is based on two separately driven wheels placed on either side of the robot body. It can thus change its direction by varying the relative rate of rotation of its wheels and hence does not require an additional </span>steering<span> motion.</span>
Answer:
If the observed sample mean is greater than 17.07 minutes, then we would reject the null hypothesis.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 15 minutes
Sample size, n = 10
Alpha, α = 0.05
Population standard deviation, σ = 4 minutes
First, we design the null and the alternate hypothesis
Since the population standard deviation is given, we use one-tailed z test to perform this hypothesis.
Formula:
Now,
Thus, we would reject the null hypothesis if the z-statistic is greater than this critical value.
Thus, we can write:

Thus, the decision rule would be if the observed sample mean is greater than 17.07 minutes, then we would reject the null hypothesis.
