Answer:
(c) goodness of fit
Step-by-step explanation:
Chi-square Goodness of fit is used to test how the observed value of the given event differs significantly the expected value. It means that goodness of fit is used to examine the observed sample value to the expected probability distribution.
The Chi-Square Goodness of fit is used as:
Firstly, we set up hypothesis as:
Null Hypothesis (H₀) : There is no difference between the observed value and expected value.
Alternative Hypothesis (H₁) : There is difference between the observed value and expected value.
Then we use the formula as :
where, E is expected value
and O is observed value.
The one-factor ANOVA is use to compare the mean of two or more variables.
The two-factor ANOVA is use to compare the mean difference of groups.

First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:
Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:
Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:
Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.
We can conclude that <span>
Marguerite will need 4 boards of wood.</span>

Answer:
.5 because .485 goes all the way to thousanths and the number 4 is in the tenths and its lower so the five is in the tenths and higher than 4. So that would lead you to .5 being greater.
