Answer:
Step-by-step explanation:
The z-score corresponding to a given area of a distribution, is the number of standard deviations that the values in that area have/are from the mean.
In this case, we have a STANDARD normal distribution. In a standard normal distribution, the mean is 0 and the standard deviation is 1.
The Z-score corresponding to a given area, say the 30th percentile is
X = 0 + (-0.524)(1)
Hence, the X (number of values in the given percentile - in this case, 30th) is same as the z-table or z-calculator value for the 30th percentile in ANY normal distribution.
Answer: 60 percent decrease
===========================================
Change in price = new - old = 100 - 250 = -150
The negative change means the price has gone down
Divide this change in price over the original 250 and convert to percent form
(change in price)/(original price) = -150/250 = -0.60
which converts to -60%
The negative percent change in price indicates a price decrease
So the price goes down by 60% meaning that it lost 60% of its value
Note how 60% of 250 is 0.60*250 = 150 which was the change in price computed earlier.
