Answer:
<h3>Option a) Influential point is correct.</h3><h3>∴ the point P(194,364.2) is an influential point.</h3>Step-by-step explanation:
Given that the regression equation for a set of paired data is = -23.8 + 2x. The values of x run from 100 to 400.
A new data point, P(194, 364.2), is added to the set.
From the given we can write it as y = -23.8+2x
Put x=194 in the above equation we get,
= 364.2
<h3> ∴ y(194)=364.2</h3>Hence, point P(194,364.2) is on regression line and it is not outlier.
<h3> ∴ the point P(194,364.2) is an influential point.</h3><h3>Hence option a) Influential point is correct.</h3>
