The weights of 67 randomly selected axles were found to have a variance of 3.85. Construct the 80% confidence interval for the p

VLD [36.1K]

Answer:

$3.13$

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 67

Variance = 3.85

We have to find 80% confidence interval for the population variance of the weights.

Degree of freedom = 67 - 1 = 66

Level of significance = 0.2

Chi square critical value for lower tail =

$\chi^2_{1-\frac{\alpha}{2}}= 51.770$

Chi square critical value for upper tail =

$\chi^2_{\frac{\alpha}{2}}= 81.085$

80% confidence interval:

$\dfrac{(n-1)S^2}{\chi^2_{\frac{\alpha}{2}}} < \sigma^2 < \dfrac{(n-1)S^2}{\chi^2_{1-\frac{\alpha}{2}}}$

Putting values, we get,

$=\dfrac{(67-1)3.85}{81.085} < \sigma^2 < \dfrac{(67-1)3.85}{51.770}\\\\=3.13$

Thus, (3.13,4.91) is the required 80% confidence interval for the population variance of the weights.

How to find the midpoint of a line segment with 2 given point?

lorasvet [3.4K]

If the 2 given points are endpoints, then we're in business. The formula for the midpoint is $M=( \frac{ x_{1}+ x_{2} }{2}, \frac{ y_{1} + y_{2} }{2})$ . If the endpoints of our segment are the coordinates (1,2) and (12,14), our formula would be filled in as follows: $M=( \frac{1+12}{2}, \frac{2+14}{2})$ which simplifies to (13/2, 8). See? It's pretty simple once you know how to do it.
