In order to estimate the mean number of pencils that campers at his camp carry in their backpacks, leonard randomly selects 50 out of the 200 campers at his camp and counts the number of pencils in their backpacks. will this likely give an accurate estimate of this mean? select from the drop-down menus to correctly complete the statement.
leonard's method or not give an accurate estimate of this mean did not did not include data for every sample is randomly selected from campers at his camp

Ok, Let us suppose , that 200 class X th students are going for excursion from their school.Their class teacher told them to bring Prog from their home. Teacher Randomly decides to check, Has all students bought Lunch boxes or Prog?

So, teacher started calling names of students, who were not notorious, neither naughty. The total number of students who were chosen whether they had bought lunch or not was 55. Is this will give better estimate that how many students has bought lunch with them on the day of journey?

I think yes, because Checking all students is a long as well as tedious process. So Selecting 50 or 55 students among 200 students will give better as well as accurate estimate of mean.

So, Leonard randomly selects 50 out of the 200 campers at his camp and counts the number of pencils in their backpacks.

Leonard's method is likely to give an accurate estimate of this mean since His sample is randomly selected from campers at his camp.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
