A random sample of 130 students is chosen from a population of 4,500 students. The mean IQ in the sample is 120, with a standard

barxatty [35]

Answer:

$120-2.614\frac{5}{\sqrt{130}}=118.85$

$120+2.614\frac{5}{\sqrt{130}}=121.15$

Step-by-step explanation:

Information given

$\bar X= 120$ represent the sample mean

$\mu$ population mean (variable of interest)

s=5 represent the sample standard deviation

n=130 represent the sample size

For this case we can't set a margin of error just with a % since they not specify 1.13% respect to something for this case we can omit this value

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

The degrees of freedom are given by:

$df=n-1=130-1=129$

The Confidence level is 0.99 or 99%, the significance would be $\alpha=0.01$ and $\alpha/2 =0.005$ , and the critical value would be $t_{\alpha/2}=2.614$

And replacing we got:

$120-2.614\frac{5}{\sqrt{130}}=118.85$

$120+2.614\frac{5}{\sqrt{130}}=121.15$

Calculate the ratio of ab to ac and the ratio of ad to dc . round your answers to the hundredths place. what do you notice about

yanalaym [24]

The ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.

<h3>Ratios and proportions</h3><h3 />

A ratio means a comparison of two different quantities while proportion is an equality of two ratios.

AB = 5 in
AC = 10 in
AD = 4 in
DC = 8 in

Ratio of AB to AC = 5 in : 10 in

= 5 / 10

= 1 / 2

= 1 : 2

Ratio of AD to DC = 4 in : 8 in

= 4 / 8

= 1 / 2

= 1 : 2

Therefore, the ratio of AB to AC and the ratio of AD to DC is 1 : 2 each respectively. They are equivalent ratios.
