1.- calcular la recta de regresión de los datos anotados en la siguiente tabla.

| |[pic] |Y[pic] |[pic]Y[pic]|[pic] |[pic] |
|1 |8 |7 |56|64 |49 |
|2 |6 |12 |72 |36 |144 |
|3 |4 |2 |8 |16 |4 |
|4|6 |6 |36 |36 |36 |
|5 |13 |7 |91 |169 |49 |
|6 |10 |3 |30 |100|9 |
|7 |1 |6 |6 |1 |36 |
|8 |7 |2 |14 |49 |4 |
|9 |3 |9|27 |9 |81 |
|10 |12 |11 |132 |144 |121 |
|[pic] |70 |65 |472 |624 |533 |
||7 |6.5 | | | |

472 [pic] = 472 – 455 = [pic]

624 - [pic] = 624 - [pic]= 274

[pic] = 0.0621

Bo = 6.5 –(0.0621) (7)
[pic] = 6.0653 + 0.0621[pic]
= 6.5 – 0.4347

= 6.0653

SOLUCION POR EL MAESTRO
[pic] = 7
[pic]= 6.5 [pic]= [pic]Y[pic] = 472
[pic] = 62.5

[pic]= [pic][pic]=[pic] = [pic]

[pic]
