Chapter 1: Q8P (page 1)

n=50,p=4/5.

Short Answer

Expert verified

Binomial distribution, i.e., f(x)=C(50,x)45x1550-x .

The graph is shown below

Step by step solution

01

Given Information.

n=50p=45q=15

02

Definition of Binomial distribution. 

The discrete probability distribution of the number of successes in a sequence ofn independent experiments is the binomial distribution with parameters nandp .

03

Solve binomial distribution for given values.

Binomial distribution is,

f(x)=C(n,x)pxqn-x

Substitute values,

f(x)=C(50,x)45x1550-x

Hence, binomial distribution is f(x)=C(50,x)45x1550-x.

Use power series to evaluate the function at the given point. Compare with computer results, using the computer to find the series, and also to do the problem without series. Resolve any disagreement in results (see Example 1).esinx-1x3In(1+x3ex)atx=0.00035.

Use the special comparison test to find whether the following series converge or diverge.

鈭�n=9鈭�(2n+1)(3n-5)n2-73

Use Maclaurin series to evaluate each of the following. Although you could do them by computer, you can probably do them in your head faster than you can type them into the computer. So use these to practice quick and skillful use of basic series to make simple calculations.
