Multiply 15 x 3.14. You'll get 47.1. Thats the area
The <em><u>correct answer</u></em> is:
A box and whisker plot
Explanation:
A box and whisker plot, or a box plot, displays what is called the "five number summary." This includes:
Median; LQ (lower quartile, or the median of the lower half of data); UQ (upper quartile, or the median of the upper half of data); lowest value; and highest value.
This will show the spread of data, and the mean can easily be added to this diagram.
Answer:
the slope is 2 because when you do y2- y1/x2-x1 you get 3-(-3)/1-(-2) which is 6/3 simplified to 2
Answer:
Z = -6.3
Step-by-step explanation:
Given that:
Since the alternative hypothesis is less than 0.28, then this is a left-tailed hypothesis.
Sample sixe n = 800
= 0.217
The standard error
Since this is a single proportional test, the test statistics can be computed as:
Z = -6.3
Mean of data = sum of values ÷ number of data
We have three values; 84, 87, and
Sum of values =
=
We want the value of
to give mean between 85 and 90 inclusive
Hence, the value of
is between 84 and 99 inclusive
