11. solve the problem. a company manufactures televisions in batches of 25 and there is a 1% rate of defects. find the standard deviation for the number of defects per batch.

0.7

0.9

0.5

72.8

0.5

Step-by-step explanation:

For binary distribution with parameters p (probability of getting success in each trial) and n (Total trials) , we have

We are given that ,

Total batches of televisions : n=25

The probability of defects : p= 0.01

Here success is getting defective batch .

Then, the standard deviation for the number of defects per batch will be :-

[Rounedde to the nearest tenth.]

Therefore, the standard deviation for the number of defects per batch =0.5

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
