A manufacturer knows that their items have a normally distributed lifespan, with a mean of 3.7 years, and standard deviation of 1 years. The 7% of items with the shortest lifespan will last less than how many years? Give your answer to one decimal place.

2.2 years

Step-by-step explanation:

Mean lifespan (μ) = 162 degrees

Standard deviation (σ) = 1 year

The 7th percentile of a normal distribution has an equivalent z-score of roughly z = -1.475. The lifespan, X, at the 7th percentile is given by:

The 7% of items with the shortest lifespan will last less than 2.2 years.

practice. practice. practice.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
