Imagine that a researcher appropriately conducts a two-tailed, independent-samples t test with an alpha level of 0.05 (5%). the first group has degrees of freedom equal to 19. the second group has degrees of freedom equal to 21. what is the critical value (as a t statistic) that would cut off the upper 2.5% of the corresponding sampling distribution. provide three decimal places when reporting your answer.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
