A transect is an archaeological study area that is 1/5 mile wide and 1 mile long. A site in a transect is the location of a significant archaeological find. Let x represent the number of sites per transect. In a section of Chaco Canyon, a large number of transects showed that x has a population variance o^2= 25.1 . In a different section of Chaco Canyon, a random sample of 23 transects gave a sample variance s^2= 53.3 for the number of sites per transect. Use an a=0.05 to test the claim that the variance in the new section is greater than 25.1. Verify that P-value < 0.005, will you reject or fail to reject the null hypothesis of independence? answer options: Since the P-value is less than the level of significance, we reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1. Since the P-value is less than the level of significance, we reject the null hypothesis that the variance is greater than 25.1. At 0.05 level of significance, we conclude that the variance is equal to 25.1. Since the P-value is less than the level of significance, we fail to reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1. Since the P-value is greater than the level of significance, we reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1. Since the P-value is greater than the level of significance, we fail to reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1.

Question

A transect is an archaeological study area that is 1/5 mile wide and 1 mile long. A site in a transect is the location of a significant archaeological find. Let x represent the number of sites per transect. In a section of Chaco Canyon, a large number of transects showed that x has a population variance o^2= 25.1 . In a different section of Chaco Canyon, a random sample of 23 transects gave a sample variance s^2= 53.3 for the number of sites per transect. Use an a=0.05 to test the claim that the variance in the new section is greater than 25.1.

Verify that P-value < 0.005, will you reject or fail to reject the null hypothesis of independence?

answer options:

Since the P-value is less than the level of significance, we reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1.

Since the P-value is less than the level of significance, we reject the null hypothesis that the variance is greater than 25.1. At 0.05 level of significance, we conclude that the variance is equal to 25.1.

Since the P-value is less than the level of significance, we fail to reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1.

Since the P-value is greater than the level of significance, we reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1.

Since the P-value is greater than the level of significance, we fail to reject the null hypothesis that the variance is equal to 25.1. At 0.05 level of significance, we conclude that the variance is greater than 25.1.
