The percentage of the average yearly wage is 7.53%.
<h3>What are percentages?</h3>
Percentage can be described as a fraction of an amount that is usually expressed as a number out of hundred.
<h3>What is the percentage of the average yearly wage?</h3>
Percent = (amount spent on family holiday / total yearly wage) x 100
(1644 / 21842) x 100 = 7.53%

Answer:
57.93% probability that a trip will take at least 35 minutes.
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:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
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 = 36, \sigma = 4.9](https://tex.z-dn.net/?f=%5Cmu%20%3D%2036%2C%20%5Csigma%20%3D%204.9)
What is the probability that a trip will take at least 35 minutes
This probability is 1 subtracted by the pvalue of Z when X = 35. So
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![Z = \frac{35 - 36}{4.9}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B35%20-%2036%7D%7B4.9%7D)
![Z = -0.2](https://tex.z-dn.net/?f=Z%20%3D%20-0.2)
has a pvalue of 0.4207
1 - 0.4207 = 0.5793
57.93% probability that a trip will take at least 35 minutes.
Answer:boys: median=50, mean=46
Girls: median= 33, mean=34
Step-by-step explanation:
Mean is the average. Median is the middle number. Both groups had 10 scores. Boys ranged from 15-81. Girls from 0-75; their mean & median would be less because their scores are less.
