Let x be a discrete random variable that possesses a binomial distribution with n=5 and p=0.87. What are the mean and standard d

Nookie1986 [14]

Answer:

$Mean = 4.35$

$SD = 0.5655$

Step-by-step explanation:

Given

$n = 5$

$p = 0.87$

Solving (a): Mean

$Mean = np$

$Mean = 5 * 0.87$

$Mean = 4.35$

Solving (b): Standard Deviation (SD)

$SD = np(1 - p)$

$SD = 5 * 0.87(1 - 0.87)$

$SD = 5 * 0.87 * 0.13$

$SD = 0.5655$

In a random sample of 55 newborn babies, what is the probability that 44% or fewer of the sample are boys. (use 3 decimal places

wel

<span>0.053 The standard deviation of a binomial variable is sqrt(n*P*(1-P)) where n is the sample size and P is the probability of one of the outcomes. The sample size is 55 and we'll assume that both male and female are equally likely outcomes. standard deviation = sqrt(55*.5*.5) = 3.7081% 44% is 1.6181 standard deviations away from the mean of 50%. Looking this up on a standard deviation chart gives .0526 probability which we'll round to 0.053</span>
