Answer:
B= 6
Step-by-step explanation:
a^2 + b^2= c^2 hypotenuse formula
Plug in what you have
8^2 + b^2= 10^2
PEMDAS
64 +b^2= 100
combine like terms
b^2=36
divide
b=6
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.
