Answer:
Correct option: (A) <em>p</em>₁ - <em>p</em>₂ < 0.
Step-by-step explanation:
The claim made by the scientist is that the proportion of female members of the National Academy of Sciences is less than the proportion of female members nationwide.
To test this claim we can difference between two proportions <em>z</em>-test.
It is assumed that <em>p</em>₁ is the proportion of women in the National Academy of Sciences and <em>p</em>₂ is the proportion of women nationwide.
Then we nee to test whether <em>p</em>₁ - <em>p</em>₂ < 0 or not.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of women in the National Academy of Sciences is not less than the proportion nationwide, i.e. <em>p</em>₁ - <em>p</em>₂ ≥ 0.
<em>H₀</em>: The proportion of women in the National Academy of Sciences is less than the proportion nationwide, i.e. <em>p</em>₁ - <em>p</em>₂ < 0.
Thus, the correct option is (A).

Step-by-step explanation:
Answer:
An = A0 + 100 * n - (An-1) * 0.10
Step-by-step explanation:
Tenemos una regla recursiva para una secuencia es una fórmula que nos dice cómo avanzar de un término a otro en una secuencia. Por lo tanto debemos buscar a An.
Hay un valor inicial que es 5000, una ganancia y una perdida de clientes, que podemos representar así:
An = 5000 + Ganancia - Perdida
Inicial = A0 = 5000
Ganancia = 100, pero cómo sucede cada año, sería: 100 * n
Perdida = 10% de los miembros actuales, si al principio son 5000 por lo tanto A0 * 0.10, pero en este primer caso es que es A0, pero en general serían An-1
reemplazando:
An = A0 + 100 * n - (An-1) * 0.10
