I'll just make my own two-way relative frequency table. A two-way relative frequency table is called such because each value is computed based on the total of the number of the whole table.
I'll just use codes to make the table fit in this screen.
A B C TOTAL
1 </span>30 16 <span>44 90</span><span>
2 </span>22 60 <span>28 110 </span><span>
TOTAL 52 76 72 200
Two-way relative frequency table:
</span><span> A B C TOTAL
1 </span>30/200=0.15 16/200=0.08 44/200=0.22 90/200=0.45<span>
2 </span>22/200=0.11 60/200=0.30 28/200=0.14 110/200=0.55 <span>
TOTAL 52/200=0.26 76/200=0.38 72/200=0.36 200/200=1.00
</span><span>
Among the given choices, my answer would be the 1st choice.
</span><span>Summer vacation Camping Traveling out of state Activities in local area Row totals At least one child under 16 0.15 0.08 0.22 0.45 All children 16 or older 0.11 0.30 0.14 0.55 Column totals 0.26 0.38 0.36 1

It would not be reasonable for Johnny to have a negative amount in the investment. This is because you cannot earn negative dollars. And he is not spending money in this case. Therefore, it is unreasonable for him to have a negative number for this situation.
Answer:
clearly the value of the test statistics shows that there are no enough evidence to support the claim that the proportion of the grads are the same.
Step-by-step explanation:
lets prove the statement by counter example, where if we have found the statement to be false for one then we conclude that it is false for all.
first lets explain what proportion is all about; proportion can be explained as the numerical relationship that compares things together.
in particular lets take grade A proportional to grade B which implies that 18:20
clearly if we observe here grade A is not same proportion with grade B. hence we conclude that there are no enough evidence to support the professor's claim.
