A teacher records the amount of time it took a random sample of students to finish a test and their scores on that test. Let x be the score and y be the amount of time. Conduct a hypothesis test of the claim that there is a linear correlation between the variables, using a 0.10 level of significance. Find the PERCENTAGE OF THE VARIANCE IN THE Y-VALUES THAT CAN BE EXPLAINED BY THEIR LINEAR RELATIONSHIP WITH THE X-VALUES.

hello your question has a missing table attached below is the missing table

Answer : 0.55%

Step-by-step explanation:

The complete table related to the answer given above is attached below

using a 0.10 level of significance the percentage of the variance in the Y-values that shows a linear relationship with the X-values = 0.55%

The values for X^2 , y^2  and x*y is determined an entered into a table ( attached below as well )

answer:

a=9

step-by-step explanation: lmk if you need a explanation

the answer is -1 1/5, also a

hope i
