Please help!!<br><br> The solution of the equation is x = ?<br> .
LUCKY_DIMON [66]

Answer:

as below

Step-by-step explanation:

\frac{2}{7} = \frac{6x}{4x + 17}

2(4x + 17) = 7(6x)

8x +34 = 42x

34 = 42x-8x

In a study of 24 criminals convicted of antitrust offenses, the average age was 60 years, with a standard deviation of 7.4 years
Alexxandr [17]

Answer: <u>56.9</u> years to <u>63.1</u> years.

Step-by-step explanation:

Confidence interval for population mean (when population standard deviation is unknown):

\overline{x}\pm t_{\alpha/2}{\dfrac{s}{\sqrt{n}}}

, where \overline{x}= sample mean, n= sample size, s= sample standard deviation, t_{\alpha/2}= Two tailed t-value for \alpha.

Given: n= 24

degree of freedom = n- 1= 23

\overline{x}= 60 years

s= 7.4 years

\alpha=0.05

Two tailed t-critical value for significance level of \alpha=0.05 and degree of freedom 23:

t_{\alpha/2}=2.0687

A 95% confidence interval on the true mean age:

60\pm (2.0686){\dfrac{7.4}{\sqrt{24}}}\\\\\approx60\pm3.1\\\\=(60-3.1,\ 60+3.1)\\\\=(56.9,\ 63.1)

Hence, a 95% confidence interval on the true mean age. : <u>56.9</u> years to <u>63.1</u> years.
