Step-by-step explanation:
Responder:
3 / 4x + 1/2 = x
Explicación paso a paso:
Dado que:
Capacidad total = x
Volumen inicial = cierta fracción * capacidad total
Volumen adicional agregado para llenar = 1/2
Por eso,
Inicial. Volumen + volumen adicional = volumen total
De las opciones:
Un volumen inicial de 3 / 4x
Volumen adicional de 1/2
Volumen total = x
Sumar todo hace que la ecuación:
3 / 4x + 1/2 = x
x - 3 / 4x = 1/2
Por lo tanto, la ecuación correcta de la opción es: 3 / 4x + 1/2 = x
Answer:
a. Identify the population of interest in this study.
- all the population of the country
b. Identify the sample for the study.
- 50 adults (the ones that were surveyed)
c. Identify the parameter of interest in the study.
- the parameter of interest is the people that believe that coffee shops are overpriced
d. Find and interpret a 95% confidence interval for the parameter of interest.
z score for a 95% confidence level = 1.96
margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579
95% confidence level interval:
0.4 - 0.13579 = 0.26421
0.4 + 0.13579 = 0.53579
- 95% confidence interval (0.26421 , 0.53579)
