Answer:
Step-by-step explanation:
Given that A shipment contains 6000 batteries, and 1% of them do not meet specifications.
Sample size =49
If x is the number of batteries not meeting specifications then
x is binomial with n =49 and p = 0.01
Because i) each toy is independent of the other
ii) There are only two outcomes
Probability whole shipment is accepted = Prob (X≤3)
=0.9885
Hence almost all shipments would be accepted.
2.3+3.1+1= 6.4
25÷6.4= 3.90625
3 tasks can be completed in 25 minutes.
6/4 or 1 and 2/4 thats a pretty easy question
