Question

The following sample observations were randomly selected.

  

x:	5	3	6	3	4	4	6	8
y:	13	15	7	12	13	11	9	5

1. Determine the 0.95 confidence interval for the mean predicted when x = 7. (Round your answers to 4 decimal places.)

2. Determine the 0.95 prediction interval for an individual predicted when x = 7. (Round your answers to 4 decimal places.)

Answer 1

The statistical software output for this problem is:

From above output:

a) 0.95 confidence interval:

(4.5522, 9.2921)

b) 0.95 prediction interval:

(2.2239, 11.6204)
