According to a research institution, the average hotel price in a certain year was $99.07. Assume the population standard deviation is $20.00 and that a random sample of 31 hotels was selected. Complete part d below.
d. What is the probability that the sample mean will be between $97 and $99? _______(Round to four decimal places as needed.)

Have you ever ridden a free-fall ride at an amusement park, where the riders are suspended at a terrifying height and then plummet towards the ground in free fall? These rides use a Lenz’s law mechanism to slow the drop. Explain how Lenz’s law applies to this situation and why this mechanism is ideal for such an application.

NAMIBIA, AFRICA COMPANY LAW QUESTION
Read the following scenario then draft the contract of employment.
Rita Dominic is a 27 year old Namibian Female who studied medicine at the University of Namibia, School of Medicine, Hage Geingob Campus from 2015 to 2019 respectively of which she graduated with flying colours. Rita was retained by Rhino Park Private Hospital to do her practical attachment there. Rita’s immediate supervisor was very impressed with how quick Rita excelled at her practical training and has recommended Rita for employment on permanent basis. The position which Rita is to fill is of head nurse and she will be granted ‘’benefits’’ afforded to any employee as stipulated in the Namibian Labour Act 11 of 2007.
Instruction: Rhino Park Human Resource officers heard that you are a commercial law expert and asked you to draft Rita’s employment contract (including her offer) with all relevant clauses.

Consider eruptions of Old Faithful geyser in Yellowstone National Park. The distribution of eruptions is said to be roughly normal and based on a study done in the park in 2011 has a mean time between eruptions of 93 minutes with a standard deviation of 9.5 minutes.
A)Suppose we are still studying 60 eruptions and we want to know what the longest 5% of mean times between eruptions would be. What average time would put us in the longest 5%?
B)How would your previous answer change if we were only studying 20 eruptions?
C)If we study 45 eruptions, what is the chance that a mean eruption time would differ from the true mean by less than 5 minutes?
D)If we study 45 eruptions, what is the chance that a mean eruption time would differ from the true mean by less than 1 minute?

2. According to Newton’s Law of Cooling, the rate of change of the temperature of an object can be modeled using the following differential equation:
dT/dt = k(T-TR)
where T is the temperature of the object (in ◦F), TR is the room
temperature (in ◦F), and κ is the constant of
proportionality.
On a crime show, the detective discovers a dead body in a hotel
room.
(a) Write the differential equation to describe the change in
temperature of the body if κ = −0.405 and thermostat in the hotel
room is set at 70◦F.
(b) Solve the differential equation using an appropriate method.
State the method you used and show your work.
(c) Assuming the victim was a healthy 98.6◦F at the time of the
murder, we have the initial condition that T(0) = 98.6. Find the
particular solution to the IVP.
(d) If the body temperature is 85◦F when the crime scene is
discovered, how long has the victim been dead? (Assume t is
measured in hours.)
