Answer:
D) the standard error for her sample is 15
Step-by-step explanation:
Samantha is 95% certain that between 50% and 70% of the first year students agree that they should be able to bring a car to campus.
Here
- 95% is the confidence level.
- The range between 50% and 70% indicates 95% confidence interval.
- 60% is the average proportion of the first year students at her university think they should be able to bring a car to campus.
- 10% (0.1) is the margin of error from the mean
Since standard error can be obtained by dividing margin of error by the z-statistic of the confidence level which is 1.96. The standard error for her sample
does not equal to 15.
Answer: 49.09 cm2
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Circumference of a circle = π x diameter = 3.14159x 3 1/8 = 9.81746 in
The circumference of the can is equal to the length of the rectangular label:
Surface area (S)= circumference(length) x height
Replacing with the values given:
S = 9.81746 x 5 = 49.09 cm2
Feel free to ask for more if needed or if you did not understand something.
