for science class, a student recorded the high and low temperatures, in fahrenheit, over a ten day period in september. the data is shown in the table.

low temperature, x 26 28 30 32 34 35 37 38 41 45

high temperature, y 49 50 57 54 60 58 64 66 63 72

a) what is the correlation for a linear model of this data? round to the nearest hundredth. r =

b) ten high and low temperatures in october are recorded and have a correlation coefficient of 0.89. in which month is there a stronger correlation between the high and low temperatures? explain your answer.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
