Suppose a study was done looking at the level of community closeness that arises after natural disasters. The researchers looked at different neighborhoods and rated them on how close people were with their neighbors. They found that the closeness scores for four neighborhoods were as follows

: 71 84 62 51 11.

A.Calculate the mean of the scores and use it to calculate the sum of squares for these four observations

b. Calculate the variance and the standard deviation for these four observations. Be sure to label which number is standard deviation and which is variance.

C. Conceptually, explain what the standard deviation refers to, in the context of this specific problem. Be sure to refer specifically to the variables described.

Please i need only C
