They have decided to marry. They have consulted with
Tony​ (their tutor) to assist in estimating the cost of having
a wedding in​ Sydney, Australia.
Tony created the table below. It shows the costs of other

people invited to the wedding​ ("attendees")
a. Determine the regression​ equation?
b. What the slope indicates?
c. What the Y intercept indicates?
d. Identify and consider the meaning of the coefficient of
determination ​(R2​) for this problem
e. Test the equation for statistical significance by examining
the population slope. Use a
0.05 level of significance. State the null and alternative
hypotheses the test.
Determine the test​ statistic:
Determine the​ p-value.
State the conclusion.
Determine the 95​% confidence interval estimate of the
population slope.
If Linda an Kris are planning to invite 175 ​guests, how much
should they estimate for the cost of the​ wedding?
