You may need to use the appropriate appendix table or technology to answer this question.

Given are five observations for two variables,
x
and
y. (Round your answers to two decimal places.)

x_i	1	2	3	4	5
y_i	4	8	4	11	13

(a)

Use

s_ŷ*
= s

(x* − x)²

Σ(x_i
− x)²

to estimate the standard deviation of

ŷ*

when

x = 5.

(b)

Use

ŷ* ± t_?/2s_ŷ*

to develop a 95% confidence interval for the expected value of
y
when

x = 5.

(c)

Use

s_pred
= s

1 +

(x* − x)²

Σ(x_i
− x)²

to estimate the standard deviation of an individual value of
y
when

x = 5.

(d)

Use

ŷ* ± t_?/2s_pred

to develop a 95% prediction interval for
y
when

x = 5.
