Jim Tree sells trees. The mean length of the trees purchased was 68 inches with a standard deviation of 10 inches. Jim wants to

Zepler [3.9K]

Step-by-step explanation:

We know that,

$Z=\dfrac{X-\mu}{\sigma}$

Where,

X = raw score = 84

μ = mean = 68

σ = standard deviation = 10

Putting the values,

$Z=\dfrac{84-68}{10}=1.6$

The percent of his sales that were less than or equal to 84 inches, is

$P(Z\leq 1.6)=0.9452=94.52\%\approx 94.5\%$

Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
