Find the 90% confidence interval for the population standard deviation given the following.
lions [1.4K]

Answer:

b. 2.01 < σ < 2.81

Step-by-step explanation:

The 90% confidence interval for the population standard deviation is calculated as:

\sqrt{\frac{(n-1)*s^{2} }{X^2_{\alpha/2 } } }    < σ < \sqrt{\frac{(n-1)*s^{2} }{X^2_{1-\alpha/2 } } }

Where n is equal to 51, s is equal to 2.34, \alpha is 10%, X^{2} _{\alpha /2} is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of \alpha /2 in the right tail and X^{2} _{1-\alpha /2} is the value for the Chi squared distribution with n-1 degrees of freedom that has a probability of 1-\alpha /2 in the right tail.

So, replacing n by 51, s by 2.34, X^{2} _{\alpha /2} by 67.50 and X^{2} _{1-\alpha /2} by 34.76, we get that the The 90% confidence interval is equal to:

\sqrt{\frac{(51-1)*2.34^{2} }{67.50} } } < σ <\sqrt{\frac{(51-1)*2.34^{2} }{34.76} } }

2.01 < σ < 2.81

Find the distance between each pair of points. round your answer to the nearest tenth.
goldenfox [79]

Answer:

5.4

Step-by-step explanation:

To find the distance between each pair of points, we use the distance formula, which is:

d = \sqrt{(x_{2}-x_{1})^2 + (y_{2} -y_{1})^2  }

So we have

x_{1} = 2\\ x_{2} = 4\\y_{1} = 8\\y_{2}=3

When we plug in the values into the formula we get:

d = \sqrt{(4-2)^2 + (3-8)^2}

d = \sqrt{4 + 25}\\ =\sqrt{29}\\ =5.4
