Assume that there is a 6% rate of disk drive failure in a year. a. If all your computer data is stored on a hard disk drive wit

Finger [1]

The easiest way to do this is calculate the probability that all drives crash, and subtract that from one. The first one is .06 squared subtracted from 1, so it’s .9964 or 99.64%. The second one is .06 cubed subtracted from 1, so it’s .9998, or 99.98 %

Use the sample data and confidence level given below to complete parts a through d.

4vir4ik [10]

Using the information given and the z-distribution, it is found that:

a) The point estimate of the population proportion is 0.5544.

b) The margin of error is: 0.0320.

c) The interval is: (0.5224, 0.5864).

d) The interpretation of the interval is: we are 95% sure that the true population proportion is between 0.5224 and 0.5864.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions has the bounds given by the rule presented as follows:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which the variables used to calculated these bounds are listed as follows:

$\pi$ is the point estimate of the population proportion.

z is the critical value.

n is the sample size.

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.
