Answer:0.8413
Step-by-step explanation:
Mean= 188, Std Dev. =20.8, Z=(x-mean)/Std Dev
P(X less than 167.2)= P(Z less than (167.2-188)/20.8)
=P(Z less than (-20.8/20.8))
=P(z less than -1)= P(Z less 1)
The value of 1 in the normal distribution table is 0.3413
So we add 0.5 to 0.3413 =0.8413
Answer: Neither
The function is not even because it doesn't have y axis symmetry. In other words, reflecting it over the vertical y axis means it doesn't line up with itself. The left half is different from the right half.
The function isn't odd either. Why not? Because rotating it 180 degrees around the origin has the function curve looking completely different. A point like (3,6) will rotate to (-3,-6) which is not on the orange curve. This is just one counter-example as to why the function is not odd.
Answer:
For question 14
The answer is x= 52%
Step-by-step explanation:
Though the box plot is not given, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.
<h3>What is a box plot?</h3>
A box plot gives a graphical (rectangular) representation of statistical data based on the following five values: minimum, first quartile, median, third quartile, and maximum.
Essentially, a box plot has the following five data descriptions:
- The leftmost whisker, showing the minimum value.
- The rightmost whisker, showing the maximum value.
- The leftmost line, showing the first quartile.
- The middle line, showing the median or the second quartile.
- The last line shows the third quartile.
Thus, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.
