A sample of 6 observations collected in a regression study on two variables, x(independent variable) and y(dependent variable). The sample resulted in the following data. SSR=60, SST=89, summation (x_i-xbar)2=28, summation (x_i-xbar)(y_i-ybar)=45.Calculate the t test statistics to determine whether a statistically linear relationship exists between x and y.

The  t test statistics = 6.1357

Step-by-step explanation:

Given that:

sample (n) = 6

r =

r =

r = 0.821

Therefore; the t test statistic can be calculated as :

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.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
