14% of all Americans suffer from sleep apnea. A researcher suspects that a lower percentage of those wholive in the inner city have sleep apnea. Of the 341 people from the inner city surveyed, 34 of them sufferedfrom sleep apnea. What can be concluded at the level of significance of a = 0.01?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Ho: ? vSelect an answer V(please enter a decimal)H1: ? vSelect an answer V(Please enter a decimal)c. The test statistic ? v(please show your answer to 3 decimal places.)d. The p-value =(Please show your answer to 4 decimal places.)e. The p-value is ? vaf. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the population proportion is not significantly smaller than 14% at a = 0.01,so there is sufficient evidence to conclude that the population proportion of inner cityresidents who have sleep apnea is equal to 14%.O The data suggest the populaton proportion is significantly smaller than 14% at a = 0.01, sothere is sufficient evidence to conclude that the population proportion of inner city residentswho have sleep apnea is smaller than 14%O The data suggest the population proportion is not significantly smaller than 14% at a = 0.01,so there is not sufficient evidence to conclude that the population proportion of inner cityresidents who have sleep apnea is smaller than 14%.h. Interpret the p-value in the context of the study.O There is a 1.6% chance that fewer than 14% of all inner city residents have sleep apnea.O If the population proportion of inner city residents who have sleep apnea is 14% and if another341 inner city residents are surveyed then there would be a 1.6% chance fewer than 10% of the341 residents surveyed have sleep apnea.O If the sample proportion of inner city residents who have sleep apnea is 10% and if another 341inner city residents are surveyed then there would be a 1.6% chance of concluding that fewerthan 14% of inner city residents have sleep apnea.O There is a 14% chance of a Type I errori. Interpret the level of significance in the context of the study.O There is a 1% chance that aliens have secretly taken over the earth and have cleverly disguisedthemselves as the presidents of each of the countries on earth.O If the population proportion of inner city residents who have sleep apnea is 14% and if another341 inner city residents are surveyed then there would be a 1% chance that we would end upfalsely concluding that the proportion of all inner city residents who have sleep apnea issmaller than 14%.O If the population proportion of inner city residents who have sleep apnea is smaller than 14%and if another 341 inner city residents are surveyed then there would be a 1% chance that wewould end up falsely concluding that the proportion of all inner city residents who have sleepapnea is equal to 14%.O There is a 1% chance that the proportion of all inner city residents who have sleep apnea issmaller than 14%.

The General Social Survey is an annual survey given to about 1500 U.S. adults selected at random. A recent survey contained the question "How important to your life is having a fulfilling job?" Of the 265 college graduates surveyed, 99 chose the response "Very important." Of the 118 people surveyed whose highest level of education was high school or less, 42 chose the response "Very important." Based on these data, can we conclude, at the 0.01 level of significance, that there is a difference between the proportion p₁ of all U.S. college graduates who would answer "Very important" and the proportion p of all U.S. adults whose highest level of education was high school or less who would answer "Very important"? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below.

Many fundraisers ask for donations using email and text messages. A paper describes an experiment to investigate whether the proportion of people who make a donation when asked for a donation by email is different from the proportion of people who make a donation when asked for a donation in a text message. In this experiment, 1.7% of those who received and opened an email request for a donation and 7.8% of those who received a text message asking for a donation actually made a donation. Assume that the people who received these requests were randomly assigned to one of the two groups (email or text message) and suppose that the given percentages are based on sample sizes of 2,000 (the actual sample sizes in the experiment were much larger). (Let p1 be the proportion who make a donation after receiving an email, and p2 be the proportion who make a donation after receiving a text message.) Find the test statistic and P-value. (Use a table or SALT. Round your test statistic to two…

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.

According to a Pew Research Center study, in May 2011, 33% of all American adults had a smart phone (one which the user can use to read email and surf the Internet). A communications professor at a university believes this percentage is higher among community college students. She selects 323 community college students at random and finds that 134 of them have a smart phone. In testing the hypotheses: Ho: p= 0.33 versus Ha: p > 0.33 Do the hypothesis test.
