Please help with this stats question

Answer 1

Explanation:

Given:

μ = 34000

τ = 2050

`\boxed{Z=(x-\mu)/(\tau) }`

(a) x₁ = 33000

`Z_1=(x_1-\mu)/(\tau)`

`=(33000-34000)/(2050)`

`=-0.49`

(b) x₂ = 37000

`Z_2=(x_2-\mu)/(\tau)`

`=(37000-34000)/(2050)`

`=1.46`

(a) x₃ = 33000

`Z_3=(x_3-\mu)/(\tau)`

`=(31000-34000)/(2050)`

`=-1.46`
