Answer:
2.28% of tests has scores over 90.
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 problem, we have that:

What proportion of tests has scores over 90?
This proportion is 1 subtracted by the pvalue of Z when X = 90. So



has a pvalue of 0.9772.
So 1-0.9772 = 0.0228 = 2.28% of tests has scores over 90.

Step-by-step explanation:
i just took the test and no one helped me i got is wrong but when you go back to review it it tells you the answer hope im not too late
The cost needed for the trip is <span>$1,750 for transportation and $3,080 for tickets to the museum.
This makes a total of: 1750 + 3080 = $4830 needed
Now, we have 385 students. Teachers will collect $12 from each. This means that the amount collected would be: 12 * 385 = $4620
Based on the above calculations, the amount needed for the trip is $4830 and the amount collected is $4620.
This means that collecting $12 from each student would not be enough for the trip.</span>
