An aptitude test has a mean score of 80 and a standard deviation of 5. The population of scores is normally distributed. What pr
konstantin123 [22]

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 \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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:

\mu = 80, \sigma = 5

What proportion of tests has scores over 90?

This proportion is 1 subtracted by the pvalue of Z when X = 90. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{90 - 80}{5}

Z = 2

Z = 2 has a pvalue of 0.9772.

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

The teachers at West Elementary are planning a field trip for 385 students. It will cost $1,750 for transportation and $3,080 fo
melomori [17]
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>
