You use a line best fit for a set of data to make a prediction about an unknown value. the correlation coefficient for your data set is -0.993. 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 you could get b. i can be a little confident; it might be close, or it might by 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 it's c, but i'm not so sure. : )

Solution:

Correlation Coefficient (r) tells the relationship between two variables, as well as line of best fit also determines the correlation between two variables. if the points are close to line of best fit it means variables are closely related with each other.

Correlation coefficient = - 0.993 , shows strong disagreement between two variables.

As line of best fit and Correlation coefficient , both of them approximately gives the same value of correlation.

Option (C) :  I can be very confident; it will be close, but it probably won't be exact is true statement.

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
