Answer:
Terrance would take 4.2666 hours, Jesse would take 6.25 hours
Step-by-step explanation:
1h/12m per hour x 50m/1h is also 50m/12m per hour = 4.266 hours (round number)

Answer:
We are 90% confident that the population mean number of children per adult is between 1.80 and 1.94.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 1.87 - 0.07 = 1.80 children
The upper end of the interval is the sample mean added to M. So it is 1.87 + 0.07 = 1.94 children.
We are 90% confident that the population mean number of children per adult is between 1.80 and 1.94.
