(b) ​E: A randomly selected person finding cheese revolting. ​F: A different randomly selected person finding cheese delicious.

A. E cannot affect F because​ "person 1 finding cheese revolting​" could never​ occur, so the events are neither dependent nor independent. B. E can affect the probability of F because the people were randomly​ selected, so the events are dependent. C. E cannot affect F and vice versa because the people were randomly​ selected, so the events are independent. D. E can affect the probability of​ F, even if the two people are randomly​ selected, so the events are dependent.

pat has three pieces of fabric that measure 3/6 5/6 and 2/6 yards long . write the lengths in order from least to greatest
Harrizon [31]
The least to greatest would be 2/6, 3/6, 5/6.
As they all have the same denominator you look at the numerator to figure out the least to greatest. 2/6 is the shortest yard and 5/6 is the longest yard so it would be greater than 2/6.

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.
