A chemical bond<span> is a lasting attraction between </span>atoms<span> that enables the formation of </span>chemical compounds<span>. The bond may result from the </span>electrostatic force<span> of attraction between atoms with opposite charges, or through the sharing of electrons as in the </span>covalent bonds<span>. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or </span>ionic bonds<span> and "weak bonds" such as </span>Dipole-dipole interaction<span>, the </span>London dispersion force<span> and </span>hydrogen bonding<span>.</span>

A computer manufacturing company has sent a mail survey to 2,800 of its randomly selected customers that have purchased a new la

vodka [1.7K]

Answer:

The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).

Step-by-step explanation:

We have to calculate a 96% confidence interval for the proportion.

We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.

The sample proportion is p=0.8.

$p=X/n=640/800=0.8$

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.8*0.2}{800}}\\\\\\ \sigma_p=\sqrt{0.0002}=0.014$

The critical z-value for a 96% confidence interval is z=2.054.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_p=2.054 \cdot 0.014=0.03$

Then, the lower and upper bounds of the confidence interval are:

$LL=p-z \cdot \sigma_p = 0.8-0.03=0.77\\\\UL=p+z \cdot \sigma_p = 0.8+0.03=0.83$

The 96% confidence interval for the population proportion is (0.77, 0.83).
