Answer:
The value of the test statistic is 6.642.
Step-by-step explanation:
A Chi-square test for Goodness of fit will be used to determine whether the viewing audience proportions changed.
The hypothesis is defined as:
<em>H₀</em>: The viewing audience proportions has not changed.
<em>Hₐ</em>: The viewing audience proportions has changed.
The test statistic is:
Here,
O = observed frequencies (O - E)²
E = expected frequencies = n × p
The table below shows the observed and expected frequencies.
Compute the test statistic value as follows:
Thus, the value of the test statistic is 6.642.
Answer:
I can't see three but I'll answer the first two.
Step-by-step explanation:
Number one: The first, third, and fifth options are correct,
Number two: A is correct because if you divide 3/4 you get 0.75. Check by multiplying 0.75 for one by 4 and you get three dollars.
So for three, one pound of pears costs two dollars. That is consistent with the graphs. Pick the answer that states that the best.
From the sizes give,
there are:
3 - 9's
3 - 8's
1 - 7
2 -10's
