Acompany 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.
o 0.7
o 0.9
00.5
o 72.8

The standard deviation for the number of defects per batch is 0.5

In binomial distribution, standard deviation is given as:

Where "n" is the number of observations

"p" is probability of getting success

We are given that ,

Total batches of televisions : n = 25

The probability of defects : p = 1% = 0.01

Here success is getting defective batch

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

Plugging in values in formula, we get

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

homozygous. one is homozygous, while two is heterozygous.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
