California, Connecticut, and New York are states with laws requiring that cars have license plates on the front and rear. The author randomly selected cars in those states and the results are given inthe accompanying table. Use a 0.01 significance level to test the claim of independence between the state and whether a car has front and rear license plates.

Researchers wanted to determine if there was an association between daily cantaloupe consumption and the occurrence of colon cancer. The researchers looked at 93,417 women and asked them to report their cantaloupe-eating habits. The researchers also determined which of the women had adenocarcinoma. After their analysis, the researchers concluded that consumption of two or more servings of cantaloupe per day was associated with a reduction in adenocarcinoma Complete parts (a) through (c) below. (a) What type of observational study was this? Explain. O A. This was a cohort study because it identified a group of individuals to participate in the study and observed the group over a long period of time. O B. This was a cross-sectional study because all information about the individuals was collected at a specific point time O C. This was a case-control study because individuals that had a certain characteristic were matched with those that did not. (b) What is the response variable in the…
There are two main fishing spots in a certain video game, a river and a lake. In the river, out of the 57 fish that were caught, 31 of them were trout. In the lake, out of the 64 fish that were caught, 24 of them were trout. Use a significance level of a = 0.02 to test the claim that the proportion of trout in the river is greater than the proportion of trout in the lake. Let the river represent population 1, and the lake represent population 2. a.) State the null and alternative hypothesis using correct symbolic form. Ho: P1 P2 H1: P1 + P2 b.) What is the critical value? (round to two decimal places)
