-7 is the answer to this question
For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.
Step-by-step explanation:
well, it is a combination of 2 shapes.
I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.
that would be
2x2 + 6x5 = 4 + 30 = 34 cm²
but you started a valid approach too.
you "sliced" off a narrow rectangle along the whole right side. 7x2.
and that leaves now a 4x(7-2) rectangle.
so,
7x2 + 4x5 = 14 + 20 = 34 cm²
yes, this was my answer.
how did this suddenly appear as your answer ?
Answer: The hypothesis test is left-tailed test.
The parameter tested here is population mean.
Step-by-step explanation:
Given : The null and alternative hypotheses are as follows:
We can see that the parameter tested here is population mean.
Also, the type of test depends on the alternative hypothesis.
Since the alternative hypothesis is left-tailed so the hypothesis test is left-tailed test.
