Answer:
silly question has no answer
-0.2 is equal to -2/10, which can be simplified to -1/5.
Just shade in one box as 1/2 divide by 5 is 1/10
Answer:
89.44%
Step-by-step explanation:
Problems of normally distributed samples are solved using 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:
If you score 52 on the test, what percentage of test takers scored lower than you?
This is the pvalue of Z when X = 52.
has a pvalue of 0.8944.
So 89.44% of test takers scored lower than you.
