The number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.
Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for population mean is:
The margin of error for this interval is:
The information provided is:
<em>σ</em> = $569
MOE = $140
Confidence level = 95%
<em>α</em> = 5%
Compute the critical value of <em>z</em> for <em>α</em> = 5% as follows:
*Use a <em>z</em>-table.
Compute the sample size required as follows:
Thus, the number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.
Answer:
Quedan 2.083 m^3 de agua en el reservorio.
Equivalen a 2083 litros.

Los dueños del restaurante tienen un reservorio de agua cuyo volumen es de 6.25 m^3.
Si han utilizado 2/3 del reservorio, esto implica que aún quedan en el reservorio una tercera parte del volumen original (1/3).
Entonces, la cantidad de metros cúbicos (m^3) de agua que quedan en el reservorio se puede calcular como:
Este valor equivale a un volumen en litros de:
