(a)
What is the value of the standard error of the estimate? (Round
your answer to three decimal places.)
(b)
Test for a significant relationship by using
the t test. Use 𝛼 = 0.05.
State the null and alternative hypotheses.

Do not reject H0. We cannot conclude
that the relationship
between x and y is
significant.
