A student wants to compare the mean times needed to access flight information for two major airlines. 20 randomly selected students accessed one airline's Web site, and the time required to locate the flight information had a mean of 2.5 minutes and a standard deviation of 0.8 minute. 20 different randomly selected students accessed the other airline's Website, and the time required to locate the flight information on that site had a mean of 2.1 minutes and a standard deviation of 1.1 minutes. Assuming that the conditions for inference are met, which of the following statements about the p-value is true?A. The p-value is less than 0.01; therefore, there is a significant difference in mean search times on the two WebsitesB. The p-value is greater than 0.01 but less than 0.05; therefore, there is a significant difference in mean search times on the two WebsitesC. The p-value is greater than 0.05 but less than 0.10; therefore, there is a significant difference in mean search times on the two WebsitesD. The p-value is greater than 0.10; therefore, there is no significant difference in mean search times on the two WebsitesE. Since this is a matched-pairs situation, additional information is needed to perform a test of significance.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.
