We are asked to solve the formula 
for 
. Starting off, we can divide both sides by 
, so we are left with only the variable on the right-hand side. Next, we need to multiply the reciprocoal of 
, which is 
to both sides. This gives us 
, which, when simplified, gives us 
. Hope this helped and have a phenomenal day!

Answer:
The standard deviation for the number of defective parts in the sample is 1.88.
Step-by-step explanation:
The sample is with replacement, which means that the trials are independent, and thus, the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
68 defective out of 400:
This means that
From the shipment you take a random sample of 25.
This means that
Standard deviation for the number of defective parts in the sample:
The standard deviation for the number of defective parts in the sample is 1.88.
