Answer:
See explanation below
Step-by-step explanation:
We need to define the null hypothesis and the alternative hypothesis.
The null hypothesis is the hypothesis that states that the population results are actually what they claimed to be.
So, in this case, the null hypothesis (H₀) would be:<u> P(student buys a hard copy) = 0.60 P(student prints book from the web) = 0.25, P(student reads book online) = 0.15</u>
The alternate hypothesis states that the results were not the expected ones, in this case, any alternate hypothesis with different probabilities of any of the three cases will do.
<u>Hₐ= The percentages of students for any of the three cases is different (either greater or lower)</u>
Most of the information's that are required for solving the problem is already given in the question. So it is very important to read the question minutely before going for solving and getting to the desired answer.
Total number of eggs that Mary has = 216
Number of eggs that can fit in each carton = 12
Then
Number of cartons required to completely fill = 216/12
= 18
So 18 cartons are required by Mary to fill all the eggs that she has. I hope the procedure is simple enough for you to understand. You can always use this method for solving similar questions in future without requiring any kind of additional help from anybody.
B.) We say that there is a positive correlation between x and y if the x-values increase as the corresponding y-values increase
the Answer is .......... ok
Answer:
The correct answer is 4.
Step-by-step explanation:
4 is the biggest number that both numbers can be divided. 12 divided by 4 = 3 and 8 divided by 4 = 2. 12 can be divided by 6, but not 8, so 4 is the greatest common factor.
