Form a union for the following sets. K = {2, 3, 5, 8} L = {3, 5, 7}

Kisachek [45]

A union for sets means you combine the two sets together. The symbol of a union is ∪, so we can represent this question with K <span>∪ L.

You simply must combine the two sets together without repeating any of the same numbers.

K </span><span>∪ L = {2, 3, 5, 7, 8}.</span>

prohojiy [21]

Answer:

Since the Confidence is 0.90 or 90%, the value of $\alpha=0.1$ and $\alpha/2 =0.05$ , and the critical value would be $t_{\alpha/2}=1.669$

And replacing we got

$17.5-1.669\frac{4.2}{\sqrt{65}}=16.63$

$17.5+1.669\frac{4.2}{\sqrt{65}}=18.37$

For the 95% confidence the critical value is $t_{\alpha/2}=1.998$

$17.5-1.998\frac{4.2}{\sqrt{65}}=16.46$

$17.5+1.998\frac{4.2}{\sqrt{65}}=18.54$

Step-by-step explanation:

Information given

$\bar X¿ 17.5$ represent the sample mean

$\mu$ population mean (variable of interest)

s¿4.2 represent the sample standard deviation

n¿65 represent the sample size

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:

$df=n-1=65-1=64$

Since the Confidence is 0.90 or 90%, the value of $\alpha=0.1$ and $\alpha/2 =0.05$ , and the critical value would be $t_{\alpha/2}=1.669$

And replacing we got

$17.5-1.669\frac{4.2}{\sqrt{65}}=16.63$

$17.5+1.669\frac{4.2}{\sqrt{65}}=18.37$

For the 95% confidence the critical value is $t_{\alpha/2}=1.998$

$17.5-1.998\frac{4.2}{\sqrt{65}}=16.46$

$17.5+1.998\frac{4.2}{\sqrt{65}}=18.54$
