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 $t_{n-1}__{\alpha }} = 1.649$

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

$ME = 2.2962$

Vlad1618 [11]

Answer:

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!
