Step-by-step explanation:
Answer:
0.6302494097
Step-by-step explanation:
Multiply 0.95, 9 times. Not 0.95×9 though.
It would take him 5 weeks. why?
7.89*20= $156 per week
156*5 weeks= $780
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
