Answer 2

Answer:

$arithmetic \: mean \: = sum \: of \: observation \: no \: of \: observation$

Step-by-step explanation:

$given \: observation \: = 6 \: \: \: 8 \: \: 5 \: \: 7 \: \: x \: \: 4$

$mean = 7$

$7 = \frac{(6 + 8 + 5 + 7 + 4 + x)}6 \\ \\ 7 = 6 = 30x \\ x = \frac{42}{30} \: \: \: \: \: \: \: \: x = \frac{7}{5}$
