The table shows the number of absences, x, in a class and the final exam grade, y, for seven students. 1 0 2 6 4 3 3 20 y 95 90 90 55 70 80 85 Use the graphing calculator to find the correlation coefficient. (Round answer to three decimal places. Do not write 0.123 as.123.)

The photo attached has my question.

Find the value of the correlation coefficient for the data shown in the table. Round to the nearest hundredths.

A researcher finds a correlation (r) of 0.50 between height and weight. what variation in weight can be explained by the variation in height?

Please help me answer d e and f

Determine from your graph if the data shows a correlation. What would you expect the correlation coefficient to look like (close to +1, -1, or 0)? Explain

The given figure displays the relationship between golfers' scores on the first and second rounds of the 2019 Masters Tournament.   The correlation is ?=0.283.is �=0.283. The provided figure gives data on number of boats registered in Florida and the number of manatees killed by boats for the years 1977 to 2018.   The correlation is ?=0.919.is �=0.919. Explain in simple language why knowing only these correlations enables you to say that prediction of manatee deaths from number of boats registered by a regression line will be much more accurate than prediction of a golfer's second-round score based on that golfer's first-round score.

For the data set {0.7, 0.2, 0.4, 0.5), find x

Sheena obtains cash from an ATM machine. She suspects that the rate at which she spends the cash is affected by the amount of cash she withdrew at her previous visit to an ATM. To investigate this she deliberately varies the amount she withdraws. She records for her each visit to an ATM, the amount "x"(in $) withdrawn and the number of hours "y" until her next visit to an ATM.
