An article reported the results of an experiment to determine the effect of load on the drift in signals derived from a piezoelectric force plates. the correlation coefficient y between output and time under a load of 588 n was −0.9515. measurements were taken 120 times per second for 300 seconds, for a total of 36000 measurements. find a 95% confidence interval for the population correlation rho.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

there is no answer sorry!
