Explicación paso a paso:
Dados los datos: 55, 51, 60, 56, 64, 56, 63, 63, 61, 57, 62, 50, 49, 70, 72, 54, 48, 53, 58, 66, 68, 45, 74, 65, 58, 61, 62, 59, 64, 57, 63, xx, xx
Los dos valores faltantes podrían ingresarse utilizando varios métodos, incluyendo la mediana, modal y el valor medio de los datos dados en la distribución.
Aquí usaremos el valor medio.
Media (m) de los datos = suma de la observación / número de observaciones Media =
(55 + 51 + 60 + 56 + 64 + 56 + 63 + 63 + 61 + 57 + 62 + 50 + 49 + 70 + 72 + 54 + 48 + 53 + 58 + 66 + 68 + 45 + 74 + 65 + 58 + 61 + 62 + 59 + 64 + 57 + 63) / 31 = 1844/31 = 59.4 = 59 (al número entero más cercano) Entonces reemplace los valores faltantes con 59.
En otro para hacer cálculos sobre los datos, hay que reorganizarlos.
Datos ordenados: 45,48,49,50,51,53,54,55,56,56,57,57,58,58,59,59,59,60,61,61,62,62,63,63,63, 64,64,65,66,68,70,72,74
Los cuartiles de datos:
Primer cuartil (Q1) = 1/4 (33 + 1) = 1/4 (34) = 8.5
Q1 = (8º + 9º) / 2 = (55 + 56) = 111/2 = 55,5
Segundo cuartil (Q2) = Q3 - Q1 = (25.5 - 8.5) = 17th = 59
Tercer cuartil (Q3) = 3/4 (33 + 1) = 3/4 (34) = 25.5 Q3 = (25 + 26) = (63 + 64) = 127/2 = 63.5
Rango intercuartil (IQR) = 63.5 - 55.5 = 8
Mediana = Q2 = 59
Mínimo = 45
Máximo = 74
Rango = 74-45 = 29
El quinto decil:
D5 = [5 (33 +1)] / 10 = 5 (34) / 10
D5 = 170/10 = 17º valor = 59
7mo decil: D7 = [7 (33 + 1)] / 10 = 7 (34) / 10
D7 = 238/10 = 23.8 ° término D7 = 63
Percentil:
Percentil 13 (13% × 33) = 0.13 × 33 = 4.29
4to término = 50
Percentil 76: (76% × 33) = 0.76 × 33 = 25.08
25 ° término = 63
Answer:
Step-by-step explanation:
To find the slope of the line, we can look at the coefficient of x in the equation. In this case, the coefficient of x is 9/10. Therefore, the slope of the line is 9/10.
The total area of the United State will be 3,537,438.
The process of combining two or more numbers is called the Addition.
Given that;
The total land area of the United States is about 3,483,511 square miles more than the total land area of Tennessee, which is about 53,927 square miles.
Now,
Let the total area of the United State = x
Hence, We can formulate;
⇒ x = 3,483,511 + 53,927
⇒ x = 3,537,438
Thus, The total area of the United State = 3,537,438.
