A dotplot of the distribution of height for Mrs. Navard’s class is shown, along with some numerical summaries of the data. Suppose that Mrs. Navard has the entire class stand on a 6-inch high platform and then asks the students to measure the distance from the top of their heads to the ground. What are the standard deviation and IQR of the new distribution of distance?

For each of the processes in model 1, decide as a group if the molecules in the substances have more order (are more organized) before or after the reaction. circle the side of the reaction with more order.

Suppose you are making a map of stars around the sun, and you draw earth 1 cm from the sun on your map. the brightest star in the night sky is 8.6 light-years from the sun. on your map, how far would you place that star from the sun?

Ahypothesis test is conducted with a significance level of 5%. the alternative hypothesis states that more than 65% of a population is right-handed. the p-value for the test is calculated to be 0.03. which of the following statements is correct? we can conclude that more than 3% of the population is right-handed. we cannot conclude that more than 65% of the population is right-handed. we can conclude that more than 65% of the population is right-handed. we can conclude that exactly 3% of the population is right-handed. there is not enough information given to make a conclusion.
