Q10.7 In spite of the potential safety hazards, some people would like to have an Internet connection in their car. A preliminary survey of adult Americans hasestimated this proportion to be somewhere around 0.40.(a) Use the given preliminary estimate to determine the sample size required to estimate the proportion of adult Americans who would like an Internetconnection in their car to within 0.05 with 95% confidence. (Enter your answer as a whole number.)(b) The formula for determining sample size given in this section corresponds to a confidence level of 95%. How would you modify this formula if a 99%confidence level was desired?2On = p(1 - p) (1.96 ) ²On = p(1 - p) (2.58 ) ²On = p(1 - p) (2.3·P)(2.33)²1.645\2On = p(1 - p) (1.64·P) (2.05 ) 2On = p(1 - p)(c) Use the given preliminary estimate to determine the sample size required to estimate the proportion of adult Americans who would like an Internetconnection in their car to within 0.05 with 99% confidence. (Enter your answer as a whole number.)

A researcher wishes to estimate the percentage of adults who support abolishing the penny. What size sample should be obtained if he wishes the estimate to be within 3 percentage points with 99% confidence if he uses a previous estimate of 25%(?) and if he he does not use any prior estimates?
Suppose we take a sample of 2,500 blood donors from a population for which 50% (0.5) have type O+ blood. (a) Into what range of possible values should the sample proportion fall 95% of the time, according to the Empirical Rule? to (b) If the sample included only 625 donors instead of 2,500, would the range of possible sample proportions be wider, more narrow, or the same as with a sample of 2,500 donors? Explain your answer, and explain why it makes intuitive sense. The range would be with 625 donors compared to a sample of 2,500 donors since the standard deviation of the sampling distribution would be . This makes intuitive sense because if fewer donors are included in the sample, the proportion will be reliable as an estimate of the proportion.
How large a sample must a pollster take in order to estimate with 95% confidence and to within 3 percentage points, the proportion of voters who are in favor of a certain measure? Use the information that several years ago the proportion was 0.12.
Based on past data, it is known that about 20.5% of people smoke cigarettes. Suppose we take a sample of 100 people currently and find that only 12% smoke cigarettes. We want to see if there is evidence that the percentage of people who smoke cigarettes is decreasing. ROUND TO FOUR DECIMAL PLACES a. If I wanted to control my margin of error and set it to 3% with 99% confidence, what sample size would I need to take instead of the 100? b. Using my original sample size of 100, what would be the 99% confidence interval for the population proportion? c. What are the null and alternative hypotheses? d. What is the critical value at 99% confidence? e. Calculate the test statistic (using the sample of 100). f. Find the p-value. g. What conclusion would be made here at the 99% confidence level?
Dylan wants to determine a 99 percent confidence interval for the true proportion of high school students in the area who attend their home basketball games. How large of a sample must he have to get a margin of error less than 0.04? [To find n, use the value p* = 1/2 for the sample proportion and the values for z* from a z-table or t-table.] [Round to the smallest integer that works.] n =
Cora wants to determine a 90 percent confidence interval for the true proportion of high school students in the area who attend their home basketball games. How large of a sample must she have to get a margin of error less than 0.02? [Note that you don't have an estimate for p*!] [Round to the smallest integer that works.] n
Two reporters are both interested in finding the proportion of people in town who are unemployed. They each collect a random sample and use the proportion of unemployed people in the sample to run 100 simulations to determine a margin of error. The first reporter claims the proportion of unemployed people in town is 0.045 with a margin of error of 0.011. The second reporter claims the proportion of unemployed people in town is 0.037 with a margin of error of 0.02. 3) Why do you think the estimated proportion of unemployed people in town is different for the 2 reporters? 4) Why do you think the margin of error is different for the 2 reporters?
In the nation of Gondor, the EPA requires that half the new cars sold will meet a certain particulate emission standard a year later. A sample of 64 one-year-old cars revealed that only 20 met the particulate emission standard. What is the test statistic to see whether the proportion is below the requirement?
Dylan wants to determine a 95% confidence interval for the true proportion of high school students in the area who attend their home basketball games. How large of a sample must he have to get a margin of error less than 0.04? Assume we have no prior estimate of the proportion and want a conservative choice for the sample size. n =
We want to estimate, with a maximum error of .02, the true proportion of all senior medical students who plan to specialize in internal medicine, and we want 90% confidence in our results. What size sample is necessary?
The 2004 General Social Survey asked a random sample of 977 adult Americans how often they feel rushed, with three options to choose from: always, sometimes, and never. b. Are the technical conditions for conducting this test satisfied? The sample result was that 304 of the 977 people responded "always." Picture. c. Calculate the value of the test statistic by hand.Round the sample proportion and the hypothesized value of the proportion to THREE decimal places. Round the final answer to TWO decimal places. d. Using the test statistic from the previous part, calculate the p-value.Round your answer to four decimal places. p-value = ____
