bonufazy [111]

Answer:

The margin of error is  ME = 2.2962

Step-by-step explanation:

From the question we are told that

     The number of student is n = 500

     The highest amount is  A =$200

     The lowest amount is  B = $75

       The sample mean is  x = &140

The Standard deviation  of this set is mathematically evaluated as

            s =  \frac{A-B}{4}

Substituting values

            s =  \frac{200-75}{4}

            s = 31.25

The margin of error (ME) is mathematically evaluated as

            ME =  t_{n-1}__{\alpha }} *  \frac{s}{\sqrt{n} }

Where  t_{n-1}__{\alpha }} is the critical value for \alpha  = 0.05 i.e the significance level

     From the critical value table this is  t_{n-1}__{\alpha }}  =  1.649

So

       ME =  1.649  *  \frac{31.25}{\sqrt{500} }

      ME = 2.2962

Vlad1618 [11]

Answer:

d.

Step-by-step explanation:

Hello!

The population is the set of elements that you are interested in studying. In this example, the instructor wants to know the number of days Lake Tahoe Community College math students are absent from class during a quarter. To do so she will take a random sample of math students and register the number of absences of each student. Each math student is an element of the population.

Then the population is "Lake Tahoe Community College math students"

I hope it helps!
