The length of time before a seed germinates when falling on fertile soil is approximately Normally distributed with a mean of 60
PIT_PIT [208]

Answer:

b. 0.12

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 600, \sigma = 100

What is the probability that a seed will take more than 720 hours before germinating?

This is 1 subtracted by the pvalue of Z when X = 720. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{720 - 600}{100}

Z = 1.2

Z = 1.2 has a pvalue of 0.88.

1 - 0.88 = 0.12

So the correct answer is:

b. 0.12

Liula [17]
You reverse the inequality when you divide both sides by a negative number.
example:
-5x>45 (you divide both sides here by -5 to get the value of x)
answer:
x<9 (notice inequality has been has been reversed)
