Respuesta:
P = 2/7 = 0.2857 o 28.57%
Explicación paso a paso:
En primer lugar, sabemos que hay 15 bolas y necesitamos identificar cuáles son pares y superiores a 10.
Por lo tanto, debemos calcular inicialmente la probabilidad de que el número obtenido sea par.
Los números pares son 2, 4, 6, 8, 10, 12, 14
Contamos 7 números de 15 ---> P(B) = 7/15
De esos números, solo dos son mayores a 10, que son 12 y 14, así que: P(A|B) = 2/15
Para encontrar la probabilidad de obtener un número par mayor que 10:
P(A/B) = P(A|B) / P(B)
P(A/B) = 2/15 / 7/15 = 2/7 = 0.2857
Para calcular el porcentaje: 0.2857 * 100 = 28.57%.
Answer:
a) The outlier is the point located at the bottom right of the graph
b) The plotted points resemble a line that has a positive gradient
c) By conducting correlation analysis, we can determine the strength of the correlation
Step-by-step explanation:
a) The problem presents a scenario where Igor, who has recently moved, is experienced but needs to retrain medically to practice in the UK
Thus, he corresponds to the outlier situated nearest to the graph's bottom right
b) According to the scatter graph, there's a direct relationship showing that as a doctor's age increases, their annual salary tends to climb as well
Referencing the graph:
Age Salary
22 £28000
26 £30000
34 £44000
38 £42000
42 £30000
42 £46000
50 £55000
The data points follow a line demonstrating the proportional increase of salary with age.
c) To reinforce this conclusion's reliability, correlation analysis should be conducted to ascertain the relationship between age and annual incomes.
