Refer to the accompanying scatterplot. a. examine the pattern of all 10 points and subjectively determine whether there appears to be a strong correlation between x and y. b. find the value of the correlation coefficient r and determine whether there is a linear correlation. c. remove the point with coordinates (10,2) and find the correlation coefficient r and determine whether there is a linear correlation. d. what do you conclude about the possible effect from a single pair of values

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
