A political campaign is interested in whether a geographic difference existed in support for raising the minimum wage in a certain state. Polls were conducted in the two largest cities in the state about raising the minimum wage. In city 1 , a poll of 800 randomly selected voters found that 329 supported raising the minimum wage. In city 2 , a poll of 1000 randomly selected voters found that 345 supported raising the minimum wage. What type of hypothesis test should be performed? Select \( \hat{p}_{1}= \) Ex: 0.123 \( \hat{p}=\hat{p}_{2}= \) Ex: 0.123 Test statistic \( =.123 \) \( p \)-value \( = \) Ex: 0.123 Does sufficient evidence exist to support the claim that the level of support differs between the two cities at the \( \alpha=0.05 \) significance level? Select \( \checkmark \)

16. Bob made a picture graph of the marbles he and his friends have. How many more marbles does Bob have than Kayla? Explain ho you found the answer.

\#2 A survey was taken comparing the number of hours per week students spent studying and their performance on an exam. If a linear regression was performed and the correlation coefficient was -0.017 , what can be said about these results? a. As the number of hours spent studying increases, student exam performances will likely not change. b. As the number of hours spent studying inrceases, student exam performances will probably increase. c. As the number of hours spent studying increases, student exam performances will probably decrease. d. There is little evidence of a linear relationship between the number of hours spent studying and student exam performances.
