Answer:
The final position of Karel is shown on the second uploaded image
Step-by-step explanation:
On the diagram the dot represents steps to be taken by Karel

No, we don't have evidence to support that the mean completion time under new management has decreased but we can conclude that it remains at 15.5 minutes.
Given mean of 15.5 minutes , standard deviation of 1.7 minutes, sample size of 90 and sample mean of 15.4 minutes.
We can do the following study for conclusion:
Firstly the null hypothesis is
The alternate hypothesis is
since the value is less than this is a one tailed test.
Z=x bar-x/d/
where x is sample mean and d is standard deviation.
Z=15.4-15.5/1.7/
=-0.1/1.7/9.4868
=-0.560
Critical value of Z at 0.1 level of significance
Z=-1.28
We fails to reject the null hypothesis since -0.560>-1,28
Hence we don't have evidence to support that the mean completion time under new management has decreased but we can conclude that it remains at 15.5 minutes.
