Answer:
x=14.87
Step-by-step explanation:
What we want to use is pythagoras theorem:
a^2+b^2=c^2, where c is the hypotenuse
10^2+11^2=x^2
221=x^2
x=
x=14.866...
x=14.87

Answer:
a. Graph the relative frequency distribution for these results. What type of graph is ideal?
we must use bar graph
[Graph is attached with the name graph 1]
b.
Toward the Frequency Relative Frequency
volatiles 17 0.566666667
solvent 2 0.066666667
left side 7 0.233333333
right side 4 0.133333333
[Graphs is added in the attachment with the name graph 2]
c.
17/30 = 0.567
d.
se=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.567(1-0.567)}{30}}=0.091
standard error shows the variation in sampling distribution.
e.
The most plausible values for the fraction of dodder seedlings that grow toward the volatiles is:
\hat{p}\pm 2\sqrt{\frac{p(1-p)}{n}}=0.0567\pm 2(0.091)\: \: or\: \: (0.385,0.749)
This does not included the fraction expected (0.25).
