The machine described has standard deviation σ that can be fixed at certain levels by carefully adjusting the machine. What is t

Gennadij [26K]

Answer:

σ = 0.5102

Step-by-step explanation:

Y = volume filled,

µ = mean

It is a normal distribution

It follows that

0.95 = P (|Y − µ| < 1) = P (|Z| < 1 / σ)

so that

1 / σ = 1.96 ⇒ σ = (1 / 1.96)

⇒ σ = 0.5102.

Let's evaluate ~

$\qquad \sf \dashrightarrow \: \dfrac{1}{3 {}^{ - 2} \times {x}^{ - 4} \times {y}^{2} }$

plug in the values :

$\qquad \sf \dashrightarrow \: \dfrac{1}{3 {}^{ - 2} \times {3}^{ - 4} \times { - 1}^{2} }$

$\qquad \sf \dashrightarrow \: \dfrac{1}{3 {}^{ - 6} {}^{ } {}^{} }$

$\qquad \sf \dashrightarrow \: {3}^{6}$

$\qquad \sf \dashrightarrow \:729$
