hope that helps a little (:
It is 33.33 Percent greater than $135.00
What would the a represent I don't get it. If the probability of getting grape 3% so the probability of getting another color is 48.5%.
Using the Empirical Rule, it is found that 49 farms in the sample have land and building values per acre between $1100 and $1700.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the given mean and standard deviation, values between $1100 and $1700 are within 1 standard deviation of the mean, which is a percentage of 68%.
Hence, the number of farms out of 72 is:
0.68 x 72 = 49 farms.
