Answer:
No
Step-by-step explanation:
Given:
mean, μ = 11 lb
Std. deviation, σ = 2.1
Let x = the weight that separates the top 5% of the crop.
The z-score is
z = (x - μ)/σ
= (x - 11)/2.1
From standard z-table for normal distribution,
P(z=1.645) = 0.95
Therefore
(x - 11)/2.1 = 1.645
x - 11 = 1.645/2.1 = 0.7833
x = 11.783
Answer: 11.8 lb (nearest tenth)
<h3><u>Fraction to Decimal:</u></h3>
Divide the numerator (upper number) by the denominator (bottom number) on your calculator. Whatever number you get would be your decimal.
<h3><u>Decimal to Percent:</u></h3>
Take your decimal and use your calculator to multiply it by 100. Whatever number you get would be your percent. However, since it is a percent, you need to include the percentage unit.
<h3><u>Demonstration:</u></h3>
1/4 = 0.25
0.25 * 100(%) = 25%
