Nostrana [21]

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 \frac{0.1}{1.96} does not equal to 15.

Over [174]

Answer:

4 weeks

Step-by-step explanation:

Therefore the number of weeks required for both companies to arrive at the same cost can be calculated as follows

Company A = 45 + 35×4

= 45 + 140

= 185

Company B = 25 + 40×4

= 25 + 160

= 185

Hence it will cost both companies 4 weeks
