Suppose that 950 couples each have a baby find the mean and standard deviation for the number of boys in the 950 babies

nydimaria [60]

The mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

<h3>How to determine the mean and the standard deviation?</h3>

From the complete question, we have:

P(boy)= 0.5

Sample size = 950

The mean is then calculated as:

$\bar x = np$

This gives

$\bar x = 950 * 0.5$

Evaluate

$\bar x = 475$

The standard deviation is calculated as:

$\sigma = \sqrt{np(1 - p)$

This gives

$\sigma = \sqrt{950 * 0.5(1 - 0.5)$

Evaluate

$\sigma = 15.41$

Hence, the mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

F(x) = 3x2 - 7 and g(x) = x3 + 1, evaluate f(g(2)). NEED HELP PLEASEE??

Triss [41]

F(g(2)) = 3(x^3 + 1)^2 - 7 = 3(x^6 + 2x^3 + 1) - 7 = 3x^6 + 6x^3 + 3 - 7 = 3x^6 + 6x^3 - 4
