Answer:
278.88 cm
Step-by-step explanation:
Using the normal distribution, the value that separates the highest 70% of the scores in a normal distribution from the lowest 30% is:
z = -0.52.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The value that separates the highest 70% of the scores in a normal distribution from the lowest 30% is is the 30th percentile, which is <u>Z with a p-value of -0.3,</u> hence z = -0.52.

15.8 percent is your answer
The dog weighing 20 pounds on the moon will weigh 3261.9 pound on the sun.
Explanation
Let the weight on moon be x
The weight on earth=602.5% of x
weight on sun=2707% of weight on earth=2707% of 602.5% of x
given,the dog weight on moon=20 pounds
Its weight on earth=602.5% of 20
Its weight on sun=2707% of 602.5% of 20
