A Girl Scout sells boxes of cookies for the camp fund. On average, the 10 houses on Willow Avenue buy a certain number of boxes every year. Usually, the numbers of boxes bought by the households are {2, 3, 2, 2, 0, 5, 2, 1, 1, 3}. Based on this data, what is the difference between the median and the mean of the number of boxes sold ?
hello again
hello
the median is 2 mean is 21/10=2.1 so the difference is 0.10
thank you this stuff here i didnt learn yet so trying to catch up
i am trying to catch up in my own work but i have done this before.
that is why i can help you
i got another one for you
ok
car salesman sells cars with prices ranging from $5,000 to $45,000. The histogram shows the distribution of the numbers of cars he expects to sell over the next 10 years. The salesman has observed that many students are looking for cars that cost less than $5,000. If he decides to also deal in cars that cost less than $5,000 and projects selling 200 of them over the next 10 years, how will the distribution be affected? The mean will shift to the right. The mean and the median will be the same. The median will shift to the right. The mean will shift to the left.
well reading from this i first want to know what do you think it is
i know the answer but i want to see what you think it is
i think its A
well you are close but the answer is actually B
but i can understand why you did get it wrong this question is even a bit hard for me
wow i always do that pick the right answer then be wrong
lol i sometimes do the same thing
it was wrong
A comic-strip writer churns out a different number of comic strips each day. For 16 days, the writer logged the number of comic strips written each day (sorted low to high): {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}. What type of skew can be observed in this distribution? positive skew negative skew zero skew skew cannot be observed
well do you know what a skew is first
no
In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel.
so they dont touch at all
yes they do not touch at all i will attach a picture of a skew
ok
A fibration of projective space by skew lines on nested hyperboloids.
i got that picture from the wiki because it had an example of a skew
it looks complicated but finding the answer to this is hard
i am not good with skews but i will try when it says positive that means the numbers are going up when it says negative the numbers are going down so which one do you think it is
i think positive
you are correct i think but this question is hard so if i got it wrong it's because i'm not that good with skews
how many question's do you have left
it was right thank you
np
two more but im doing make up work so its a lot of five question test and the other units are like ten to 15 questions
What are the values of the median and the mean of this distribution? {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}
wow,that's alot but sadly i can only help you with the last 2 well you know what the median and mean is right
the middle
the mean is were you add all the values and then divide it by how many there are like if there was (1,2,5,6,9) add those together and the outcome would be 5/outcome
but my choices are 3.2 and 3.86 4.2 and 4.75 3 and 3.44 4.65 and 4.23
mean add em all up equaling 55 then divide by 16 cuz thats the amount of numbers u added which is 16
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
so it would be 3.4
it 3.44
3and3.44
yes
sorry i'm a little slow typing there's something going on outside my house
whats going on
i think someone robbed someones care but i'm not sure becuase he did get in the car but the alarm went off on the car
car*
ohh sheesh
so u good now gallardo or u need more help
my upstairs neighbor also got robbed and my aunts car got robbed so now im a little worried
one more question
A comic-strip writer churns out a different number of comic strips each day. For 16 days, the writer logged the number of comic strips written each day (sorted low to high): {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}. If the writer writes for one more day and comes up with 8 new comic strips, how will the skew be affected? The distribution will be skewed to the negative side. The distribution will be skewed to the positive side. The distribution will have the same mean and median. The distribution will have a mean lower than the median.
alright ask away
oh look more skews lol
dont be worried if they try it then handle it
yeah iknow
oh skews i hate em
ok this is a bit harder then the last one
ooo yeah
the distribution will be skewed to positive side i think this is the answer but i'm not sure
it is my most positive answer
so the answer is B i think
hopefully you get 100% 90% or 80%
it was right and thats the end of the test and do yall have a facebook
no,i don't have Facebook sadly the other guy left though by the way what percent did you get for your whole test
80
100 my bad
wow 100% that's awesome but sadly i cant help anymore i have to figuire out my own work
ok do what you have to do i understand
i guess tomorrow when i get on if you have any problems that you need help with i can help you but for now i cant so bye
ok for sure
