A city ballot includes a local initiative that would legalizegambling. The issue is hotly contested, and two groups decide toconduct polls to predict the outcome. The local newspaper findsthat 46% of 800 randomly selected voters plan to vote "yes,"while a college Statistics class finds 47% of 2300 randomlyselected voters in support. Both groups will create 99%confidence intervals. Assume that all voters know how theyintend to vote and that the initiative requires a majority vote topass. Complete parts a through c below.a) Without finding the confidence intervals, explain which onewill have the larger margin of error.will have the larger margin of error, atleast mainly becauseb) Find both confidence intervals.The confidence interval for the local newspaper is (%,%).(Round to one decimal place as needed.)The confidence interval for the college Statistics class(%, %).(Round to one decimal place as needed.)c) Which group concludes that the outcome is too close to call?Why?that the outcome is too closeto call, since the interval(s) obtained by this/these group(s)

Democratic and Republican presidential state primary elections differ in the way winning candidates are awarded delegates. In Republican states, the winner is awarded all the state's delegates; conversely, the Democratic state winner is awarded delegates in proportion to the percentage of votes. This difference led to an article on making your vote count. Consider scenario where you are one of five county commissioners voting on an issue, where each commissioner is equally likely to vote for or against. Complete parts and b below. a. Your vote (the decisive vote) counts only if the other four voters split, 2 in favor and 2 against. Use the binomial distribution to find the probability that your vote counts. The probability that your vote counts is 0.375. (Type an integer or a decimal. Do not round.) b. If you convince two other commissioners to "vote in bloc" (all agree to vote among yourselves first, and whatever the majority decides is the way all three will vote, guaranteeing that…

A construction company submitted a bid for a large, public construction project. The company’s management initially felt they had a 50-50 chance of getting the project. However, the department to which the bid was submitted subsequently requested additional information on the bid submitted by this company. Past experience indicates that for 75% of the successful bids but only for 40% of the unsuccessful bids the agency requested such additional information. Question: Given that the construction company was asked for additional information, what is the probability that it will get the project?

A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…

Determine whether the underlined value is a parameter or a statistic. Telephone interviews of 1,502 adults 18 years of age or older found that only 69% could identify the current vice-president. Is the value a parameter or a statistic? OA. The value is a statistic because the 1,502 adults 18 years of age or older are a population. B. The value is a parameter because the 1,502 adults 18 years of age or older are a population. C. The value is a statistic because the 1,502 adults 18 years of age or older are a sample. OD. The value is a parameter because the 1,502 adults 18 years of age or older are a sample.
