To burn off one pound,
100 cal * x = 3500
x= 35
You'll need 35 15 minutes to burn off one pound so, 525 minutes per pound, and you need to lose 7 pounds so,
525*7 = 3675 minutes OR 61.25 hours

Ok, I am stumped. Can I have some help please??

We start at line 128 and sample two-digit numbers.  The first number is 53, which is invalid.  The second is 53, which is also invalid.  Then we have 79 followed by 64, which are invalid.  Finally, we have 28, which is a valid number, followed by 40 and 11, which are also within our population.  Then we get 52, 74, 67, 90, 82, and 65, which are invalid.  Lastly, we have 23, a valid member of the population.

Our sample thus includes the members labeled 11, 23, 28, and 40.

Part F What is the mean absolute deviation for Doctor A’s data set on glasses? What is the mean absolute deviation for Doctor B’
frez [133]

There is more variability on glasses of doctor B's dataset than the glasses of doctor A's dataset

<h3>The doctors' mean absolute deviation on glasses</h3>

The dataset of doctor A is given as:

643 634 670 658 636 624 641 655 649 629

The dataset of doctor B is given as:

651 625 622 624 631 621 653 647 646 646

Using a statistical calculator, we have:

<u>Doctor A</u>

  • Doctor A: Mean Absolute Deviation (MAD) = 11.28
  • Doctor B: Mean Absolute Deviation (MAD) = 12

Hence, the mean absolute deviation is 11.28 for Doctor A’s and 12 for Doctor B’s data set on glasses

<h3>The variation of the two data</h3>

In a dataset, the larger the mean absolute deviations value, the larger the variation.

By comparison, 12 is greater than 11.28

Hence, there is more variability on glasses of doctor B's dataset than the glasses of doctor A's dataset
