Answer:

D) Survey 100 randomly selected students from the school

Step-by-step explanation:

This gives an equal chance to everybody, so it's not biased and it is of everybody that goes to his school. A is only the people on the football team so its not students in his school. Walking to school has nothing to do with the survey topic and so thats also definitely not it. C again doesn't give a fair chance to everybody, so it would be possible to get an accurate, unbiased answer. D is definitely your answer!

I hope that helps!!

Have an awesome day! :)

3) This is definitely a positive association, but the question is - is it linear? 
Since a somewhat straight line can be drawn through the points, it is linear. 

<span>Answer: positive linear association 
</span>
4) Find the slope using the formula 
m =  \frac{y2 - y1}{x2 - x1}

m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out

Oh no! It seems that their is not a pattern in the association, so its nonlinear!

Answer: Negative nonlinear association

5) <span>m = \frac{y2 - y1}{x2 - x1}
m = 80 - 66/ 5 - 3 
m = 14/2
m = 7

Positive! But is it linear??
Let us draw a graph this time. 

I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!

Answer: Positive nonlinear association

For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6 37 36 6. 9
Liula [17]

The estimated standard error for the sample is 6

Given,

Sample size, n = 36

Sample variance, s^{2} = 1296

Standard deviation, s = √1296

                                   = 36

Standard error, SE = \frac{s}{\sqrt{n} }

                              = \frac{36}{\sqrt{36} }

                              = \frac{36}{6}

                              = 6

Concept

  • Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
  • Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by 's^{2}'
  • Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’
