Answer:
At least 202.44 mm in the top 15%.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

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 question, we have that:

How many yearly mm of rainfall would there be in the top 15%?
At least X mm.
X is the 100-15 = 85th percentile, which is X when Z has a pvalue of 0.85. So X when Z = 1.037.




At least 202.44 mm in the top 15%.
905 pounds is greater than grams.
Hope this helps (:
Answer:
Yes, it is a matched pairs design.
Step-by-step explanation:
Assuming that the twins used in the experiment are identical, this can be treated as a matched pairs designed. Although there are two individuals receiving different treatments, they are genetically similar enough for this to be considered a matched pairs design (One individual subjected to two different treatments).
