Answer:
Its malleable
Step-by-step explanation:
Its too easy
1/12 because if he first picked A, that would be a 1/4 chance. If he then picked B that would have been a 1/3 chance 3x4 = 12 so 1/12
Answer: False
The Fermi Process is a fast way to calculate an estimate (usually done with mental math or math you can do on the back of an envelope or napkin). It's unlikely you'll get the exact answer, though you should be fairly close. To make the math more simple, rounding is done.
Answer:
The supplier is less accurate than they have claimed
Step-by-step explanation:
Given that:
95% confidence interval of supplier's claim :
(20.45, 21.05)
Mean = (20.45 + 21.05) /2 = 41.5 / 2 = 20.75
Error margin = (upper bound - mean) = 21.05 - 20.75 = 0.30
95% confidence interval of your sample :
(20.48, 21.02)
Mean : (20.48 + 21.02) /2 = 41.05 / 2 = 20.75
Error margin = (upper bound - mean) = 21.02 - 20.75 = 0.27
0.3 > 0.27
From the calculations made, the mean are the same, but the error margin of supplier is higher, thus it could be concluded that the supplier is less accurate than they have claimed
