Answer:

B. 28 hr 45 min

Step-by-step explanation:

To find the answer we can do the following:

3 + 2 = 5 (number of hrs per day)

5 * 5 = 25 (number of hrs for 5 days without the minutes added on)

30 + 15 = 45 (number of minutes per day separate from hrs)

45 * 5 = 225 (number of minutes separate from hrs for 5 days)

225 minutes = 3 hours and 45 minutes (can be found by dividing 60 from 225)

25 hrs + 3 hrs 45 min = 28 hr 45 min

A student wants to simulate 31 ​birthdays, but she does not have a calculator or software program​ available, so she makes up 31
mihalych1998 [28]

Answer:

No, it is not okay to conduct the simulation this​ way.

Step-by-step explanation:

In statistics, simulation refers to a technique that is employed to model random events so that the results obtained from using the simulation is significantly similar to the results obtained from observing the real-world.

Researchers are therefore able to understand the real world when they observe the simulated outcomes.

From the description above, it can be seen that simulation is about studying random events. Therefore, a sample of the population that will be used in the simulation must be selected through a random sampling.

Random sampling refers to the sampling method that gives equal opportunity of being selected to each member of the population. This makes the sample selected through random sampling technique to be an unbiased representation of the total population.

As a result, making up 31 numbers between 1 and 365 by the student is not a random sampling, because his method may favor some numbers over others. It is therefore a defective method of carrying out simulation.

 Therefore, the it is not okay to conduct the simulation this​ way.

I wish you the best.
