Answer:
Exactly, It would be this: 8.99543738355
. But rounded is 9 or 8.99
54-6 = 48
48/4 (Alex-twice, Jennifer, Shannon)
48/4= 12
Alex- 12 x 2 = $24
Jennifer- 12 = $12
Shannon- 12+6 (the 6 I subtracted 54-6) = $18
Answer:
The limit that 97.5% of the data points will be above is $912.
Step-by-step explanation:
Problems of normally distributed samples can be 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 problem, we have that:

Find the limit that 97.5% of the data points will be above.
This is the value of X when Z has a pvalue of 1-0.975 = 0.025. So it is X when Z = -1.96.
So




The limit that 97.5% of the data points will be above is $912.
