Description: Fill in the blanks to complete an interpretation of the confidence interval forthe regression slope. If you enter any numbers, be sure to round themcorrectly.The average petalis expected to go (enter up or downin the next blank)by betweenandcm when

we know that there is unit change in dependent variable when there is unit change independent variable .hence from above table at 95% level of confidenceThe average petal length is expected to go up by between 2.130 and 2.333 cm when when the petal width goes up by 2.231.
