Answer:
D - It is impossible to make a judgment with the given information.
Step-by-step explanation:
The fact that 1200 births were randomly selected and only 599 of such picks are girls does not give enough information on whether the birth is significantly high, low or neither. We must have other information to test for significance of the births proportion.
All we know is that;
Proportion of girls birth (p) = 599/1200 = 0.499. And by default, the proportion of male births (q) will be 1-p = 1-0.499 = 0.501.
If we examine the proportion closely, there seems to be no significant difference in the birth proportion.
Having said this, we cannot really imply that, the number of girls is significantly high. Or the number of girls is neither significantly low nor significantly high. Or the number of girls is significantly low.
The best subjective submission will be that, <em>there is no significant difference between girls birth and males birth.</em> The question of high or low (an alternative hypothesis) requires some further statistical test and this question does not provide further details.
Answer:
B
Step-by-step explanation:
Answer:
Los pinos ocupan 
o <em>1 millón seiscientos veinte mil metros cuadrados</em>.
Step-by-step explanation:
Una manera de resolver este problema es la siguiente:
En palabras, 
, o <em>dos kilómetros cuadrados</em> son iguales a <em>2 millones de metros cuadrados</em>.
Sabemos que:
- Estos de bosque lo ocupan hayas y pinos, y, adicionalmente,
- Las hayas ocupan
.
De esta manera, <em>la parte que ocupan los pinos es el total del bosque menos el área ocupada por las hayas</em>. Por lo tanto, el área ocupada por los pinos es:
¿Cuántos metros cuadrados ocupan los pinos?
Los pinos ocupan, entonces, o <em>1 millón seiscientos veinte mil metros cuadrados</em>.
If you keep taking 2.5% of 80,000 it can give you 2,000 Have a happy day
