2.The table below shows the height (in inches) and weight (in pounds)of eight basketball players.

Height=67, 69, 70, 72, 74, 78, 79
Weight=183, 201, 206, 240, 253, 255

what is the correlation of the set of data? Round your answer to the nearest thousandth.
A.-0.946
B.0.596
C.0.035
D.0.981

4.You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.984. How confident can you be that your predicted value will be reasonably close to the actual value?

A.I can't be confident at all; this is about as close to a random guess as you can get.

B.I can be a little confident ; it might be close, or it might be way off.

C.I can be very confident; it will be close, but it probably won't be exact.

D.I can be certain that my predicted value will match the actual value exactly.

I think
#2.B
#4.C
(Please correct me if im wrong)

that's the correct table, sorry for the typo. and I think #2 is D and #4 is C am I correct? please correct me if im wrong

To calculate the correlation in the given data, you can use the correlation coefficient formula.

For question 2, calculating the correlation coefficient involves two steps:
Step 1: Calculate the sum of products of the differences between each height and the mean height, and each weight and the mean weight.
Step 2: Calculate the product of the standard deviations of height and weight.

Once you have these values, you can use the correlation coefficient formula:
Correlation Coefficient = (Sum of products of differences) / (Product of standard deviations)

For question 4, the correlation coefficient of 0.984 indicates a strong positive correlation between the data. This means that there is a high likelihood that the predicted value will be reasonably close to the actual value. However, it is important to note that the correlation coefficient alone does not guarantee an exact match between the predicted and actual values, so option C (I can be very confident; it will be close, but it probably won't be exact) is the most accurate choice.

Your answers are correct:
2. B
4. C

You show the Ht. of only 7 players and

the Wt. of only 6 players.

Height=67, 69, 70, 72, 74, 74, 78, 79

Weight=183, 201, 206, 220, 226, 240, 253, 255
