Scenario 2
A bowl of rice (with an unknown initial temperature) is taken off the stove and placed
on the table in a room of 28°C.
5min, from taking the bowl off the stove, the temperature the temperature of the rice is
62°C.
10min, from taking the rice off the stove, the temperature of the rice is 52°C.
Determine:
a) the initial temperature of the bowl of rice

When the ball has traveled a distance of

Combine the information in the problem and the chart using the average balance method to solve the problem.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
