How long does it take to commute from home to work? It depends on several factors including the route, traffic, and time of departure. These times tend to be fairly close to symmetrical and mound-shaped. The data listed below (in minutes) is for a random sample of eight trips. Construct a
95%
confidence interval for the population mean time of all such commutes.

A) What is the mean for this set of data?
B) Confidence Interval: (
nothing
,
nothing
)
(round all answers to two decimal places)
C) The mean commute for professor St. John is 45 minutes. Does she have the same commute as the population?
A.
She has the same commute because 45 is the same as the sample mean.
B.
She does not have the same commute because 45 is not the same as the sample mean.
C.
She does not have the same commute because 45 is not within the interval.
D.
She has the same commute because 45 is within the interval.

How long does it take electrons to get from the car battery to the starting motor?...
How long does it take electrons to get from the car battery to
the starting motor? Assume the current is 149 A and the electrons
travel through copper wire with cross sectional area 36.3 mm2 and
length 82 cm . The mass density of copper is 8960 kg/m3 and the
molar mass is 63.5 g/mol . Avogadro’s number is 6.022 × 1023 .
Assume that each copper atom contributes one conduction electron.
Answer in units of min.

How long does it take to send a 15 MiB file from Host A to Host
B over a circuit-switched network, assuming:
- Total link transmission rate = 49.7 Gbps.
- Network is FDM, with 7 permitted users, each with an equal
bandwidth share.
- A link connection requires a setup time of 84.5 ms.
Your answer should be in miliseconds (ms) with one decimal place,
and without the unit (e.g. "140.6" without the quotes)

A family comes home from a long vacation with laundry to do and
showers to take. The water heater has been turned off during
vacation. If the water heater has a capacity of 49.1 gallons and a
4610 W heating element, how much time is required to raise the
temperature of the water from 18.8°C to 62.1°C? Assume that the
heater is well insulated and no water is withdrawn from the tank
during this time.
