Answer 2

7.51

(rounded to 2 decimal places)

Explanation:

The formula for standard deviation of binomial distribution is shown below:

`\sigma=√(n*p*(1-p))`

Where
`\sigma` is the standard deviation

n is the sample size

and p is probability of success

Given n = 1000 and p =0.94, we can plug into the formula to find the standard deviation:

`\sigma=√(n*p*(1-p))\\\sigma=√(1000*0.94*(1-0.94))\\\sigma=7.51`
