Statistic. 10.59 A hospital conducted a study of the waiting
10.59 A hospital conducted a study of the waiting time in its Emergency room. The hospital has a main campus and three Satellite locations. Management had a business objective of reducing waiting time for emergency room cases that did not require immediate attention. To study this, a random sample of 15 emergency room cases that did not require immediate attention at each location were selected on a particular day, and the waiting times (measured from check-in to when the patient was called into the clinic area) were collected and stored in ERWaiting . a. At the 0.05 level of significance, is there evidence of a difference in the mean waiting times in the four locations? b. If appropriate, determine which locations differ in mean waiting time. c. At the 0.05 level of significance, is there evidence of a difference in the variation in waiting time among the four locations? … read more

The chart below shows the current speed of the Niagra river
the chart below shows the current speed of the Niagra river taken at different times on a particular day. There were no abnormal flows that varied from the speeds shown in the chart.time 3:00pm =Speed 7.2 time 3:10pm = Speed 7.9 time 3:20pm = speed 8.2 Time 3:30pm =speed 7.6 time 3:40pm = speed 7.8A. Use trapezoids to estimate the river's average current speed from 3:00pm until 3:40pmB. at what time or times during the given interval would you expect the river's actual velocity to match the estimated average velocity?C. A stick is thrown into the river at 3:00pm at the location of the measuring device and it travels along with the river's current. Approximate how far downriver the stick will be at 3:40pm? use calculus to support your answer.D. What is the stick's average acceleration from 3:00pm to 3:40pm? … read more

Got calculus questions? Ask a mathematics Expert.


The Experts on JustAnswer regularly handle advanced mathematics questions such as:


  • My bell curve is very skewed right, how do I determine what percent are deviations if the bell curve is not standard?
  • How do I find the critical value za/2 that corresponds to a confidence interval with a = 0.07?
  • Can a nonstandard normal distribution be used to find the probability that when one digit is randomly generated, it is less than 3?
  • How do I find the equation of the regression line for a data set?
  • How do you calculate mass when given force, frictional force, and driven force?

To make the best use of your time with the mathematician, you should be ready to provide details for your question such as:


  • A complete description of the advanced mathematics problem.
  • Any data sets, charts, or graphs associated with the problem.

With this information ready, you will be able to get the best advice from the Expert.
