Tolong dijawab dengan caranya
Jawaban:
mis: nilai ke-5 = x
a. jika x ≤ 6 ==> median = 7
median = rata2
7 = ⅕(7+8+6+8+x)
35 = 29+x
x = 6
b. jika 6 < x ≤ 7 ==> median = 7
hasil = no. a
c. jika 7 < x ≤ 8 ==> median = x
x = ⅕(7+8+6+8+x)
5x = 29+x
x = 7,25
d. jika x > 8 ==> median = 8
8 = ⅕(7+8+6+8+x)
40 = 29+x
x = 11 (tidak mungkin)
maka x = 6 atau 7,25
