1 answer:

3 0

The answer is x < 12

1) Minus 6 from both sides of the inequality

2) Multiply both sizes by 4

3) Divide both sides by -3

4) Swap the direction of the inequality (You always do this when you multiply/divide both sizes of an inequality)

5) You should have x < 12

Suppose weight of a baby less than 2 months is normally distributed with mean 11.5 lbs and standard deviation 2.7 lbs, what prop

Lera25 [3.4K]

Step-by-step explanation:

First calculate the z-score.

z = (x − μ) / σ

z = (11.07 − 11.5) / 2.7

z ≈ -0.16

From a z-score table:

P(z<-0.16) = 0.4364

The proportion of babies that weigh less than 11.07 lbs is 0.4364.
