c. 9.5 lb < mu < 11.1 lb.
Step-by-step explanation:
Confidence interval can be stated as M±ME where
- M is the sample mean (10.3)
- ME is the margin of error
margin of error (ME) around the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- s is the standard deviation of the sample (2.4)
- N is the sample size (37)
Putting thesenumbers in the formula we get:
ME=
≈ 0.7733 ≈ 0.8
Then the 95% confidence interval would be 10.3 ± 0.8

Answer:
Step-by-step explanation:
<u>We know that the perimeter is the sum of side lengths.</u>
<u>Substitute the values and solve for x:</u>
- x + 2x - 2 + 3x + 1.5 = 11.5
- 6x - 0.5 = 11.5
- 6x = 12
- x = 12/6
- x = 2
