1. [-/3 Points] DETAILS DEVORESTAT9 9.4.049.S. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Consider the following two questions designed to assess quantitative literacy. 1. What is 15% of 1000? 2. A store is offering a 15% off sale on all TVs. The most popular television is normally priced at $1000. How much money would a customer save on the television during this sale? Suppose the first question is asked of 200 randomly selected college students, with 162 answering correctly; the second one is asked of a different random sample of 200 college students, resulting in 141 correct responses. Carry out a test of hypotheses at significance level 0.05 to decide if the true proportion of correct responses to the question without context exceeds that for the one with context. (Use p, for the true proportion students who answered the question without context correctly and p, for the true proportion of students who answered the question with context correctly.) LA USE SALT State the relevant hypotheses. O Ho: P1 - P2 = 0 Ha : P1 - P2 > 0 O Ho: P1 - P2 = 0 H: P1 - P2 0 H: P 1 - P2 = 0 OHO: P1 - P2 0 O Ho: P1 - P2 = 0 Ha: P1 - P2 0 O Ho: P1 - P2 = 0 Ha : P 1 - P 2 20 Calculate the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) P-value = State the conclusion in the problem context. O Fail to reject Ho. There is insufficient evidence to suggest that a higher proportion of men will experience one or more sexual side effects if told that a potential side effect of the BHP treatment is erectile dysfunction than if they weren't told of this potential side effect. O Fail to reject Ho. There is sufficient evidence to suggest that a higher proportion of men will experience one or more sexual side effects if told that a potential side effect of the BHP treatment is erectile dysfunction than if they weren't told of this potential side effect O Reject H . There is insufficient evidence to suggest that a higher proportion of men will experience one or more sexual side effects if told that a potential side effect of the BHP treatment is erectile dysfunction than if they weren't told of this potential side effect. O Reject Ho. There is sufficient evidence to suggest that a higher proportion of men will experience one or more sexual side effects if told that a potential side effect of the BHP treatment is erectile dysfunction than if they weren't told of this potential side effect.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Do teachers find their work rewarding and satisfying? An article reports the results of a survey of 398 elementary school teachers and 269 high school teachers. Of the elementary school teachers, 222 said they were very satisfied with their jobs, whereas 125 of the high school teachers were very satisfied with their work. Estimate the difference between the proportion of all elementary school teachers who are satisfied and all high school teachers who are satisfied by calculating a 95% CI. (Use Pelementary - Phigh school. Round your answers to four decimal places.) LA USE SALT Interpret your 95% confidence interval. We are 95% confident that the difference between the proportions of elementary school teachers who are satisfied and high school teachers who are satisfied falls above the upper bound. We are 95% confident that the difference between the proportions of elementary school teachers who are satisfied and high school teachers who are satisfied falls outside these values. We are 95% confident that the difference between the proportions of elementary school teachers who are satisfied and high school teachers who are satisfied falls below the lower bound. We are 95% confident that the difference between the proportions of elementary school teachers who are satisfied and high school teachers who are satisfied falls between these values.
