Mathematics
A cognitive psychologist is interested in the Dunning-Kruger effect, the phenomenon in which people often rate their cognitive skills as being greater than they really are. He recruits a sample of 17 undergraduate students who are near the end of an entry-level macroeconomics course at his university. The students are asked to take a test worth 100 points, on which most material is based on upper-level economics concepts (in other words, it’s hard!). Once they finish the test, the students are asked to rate their proficiency level in economics on a scale of 1-10, where higher ratings indicate higher self-perceived proficiency in economics. The question at stake is whether the students’ proficiency level self-ratings predict their actual performance on a difficult economics test. Using this table, enter the data into a new SPSS data file and run a linear regression analysis to test whether proficiency level self-ratings predict scores on an economics test. Create a scatterplot with a regression line to show the relationship between the variables.

Add the contributions:
5,358 + 2,834 + 4,132 = 12,324 < this is the current total amount raised. subtract this from the goal, 14,000 to find out much more money is needed for the playground.
14,000 - 12,324 = 1,676
$1,676 is still needed in order to create the playground.
