Question

Find the Margin of Error for each problem:

1) *c* = .95; *n* =
30; *s* = 3.5 Margin of Error=

2) *c* = .85; *n* =
18; *s* = 0.49 Margin of Error=

3) *c* = .95; *n* =
12; *s* = 12.6 Margin of Error=

4) *c* = .99; *n* =
26; *s* = 18.9 Margin of Error=

Round answers to three decimal places.

Answer #1

Build the Confidence Interval for each problem:
1) c = .95; n =
30; s = 3.5; x̅ = 57.3 Confidence
Interval= ( , )
2) c = .85; n =
18; s = 0.49; x̅ = 15.8 Confidence Interval=
( , )
3) c = .95; n =
12; s = 12.6; x̅ = 73.2 Confidence
Interval= ( , )
4) c = .99; n =
26; s = 18.9; x̅ = 1002.4
Confidence Interval= ( , )
Round answers to three decimal places.

If n=27, ¯ x (x-bar)=46, and s=9, find the margin of error at a
95% confidence level (use at least two decimal places)
If n=19, ¯xx¯ (x-bar)=48, and s=6, find the margin of error at a
95% confidence level (use at least two decimal places)
If n=16, ¯xx¯ (x-bar)=48, and s=6, find the margin of error at a
99% confidence level (use at least three decimal places)

If n=26, ¯xx¯ (x-bar)=50, and s=6, find the margin of error at a
99% confidence level (use at least three decimal places)

If n=12, ¯xx¯ (x-bar)=31, and s=8, find the margin of error at a
99% confidence level (use at least three decimal places)

If n=18, ¯ x x ¯ (x-bar)=30, and s=2, find the margin of error
at a 98% confidence level.
Assume the t distribution must be used. Give your answer to two
decimal places.

If n=32, ¯ x (x-bar)=44, and s=7, find the margin of error at a
95% confidence level (use at least two decimal places)

If n=32, ¯ x (x-bar)=49, and s=3, find the margin of error at a
95% confidence level (use at least two decimal places)

If n=18, ¯xx¯(x-bar)=40, and s=10, find the margin of error at a
99% confidence level
Give your answer to two decimal places.

If n=28, ¯xx(x-bar)=46, and s=7, find the margin of error at a
95% confidence level
Give your answer to two decimal places.

Find the margin of error for the given values of c, σ, and
n.
