- As a part of a class project, a teacher brings a jar of 200 jawbreakers of three different colors, orange, red and white. Students must estimate the number of white jawbreakers in the jar. Suppose that after the jar is shaken well, one student draws 30 jawbreakers from the jar, of which 9 are orange, 11 are red and 10 are white. Give the students sample statistic for the percent of white jawbreakers in the jar. Round to the nearest whole #.In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 37% with a margin of error of 2.5%. Describe the conclusion about p using an absolute value inequality. . That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbolic entry option will automatically convert that to ≤ . In the same way, if you type in > and then =, the symbolic entry option will automatically convert that to ≥. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).he city of Raleigh has 7000 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 400 randomly selected registered voters was conducted. 131 said they'd vote for Brown, 259 said they'd vote for Feliz, and 10 were undecided.Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown. Note: The proportion should be a fraction or decimal, not a percent. This sample statistic suggests that we might expect of the 7000 registered voters to vote for Brown.
- If 471 households were surveyed out of which 385 households have internet fiber cable, what is the sample proportion of households without fiber cable is (Round off the answer up to 3 decimal places)A researcher wishes to estimate the number of households with two computers. How large a sample is needed in order to be 90% confident that the sample proportion will not differ from the true proportion by more than 6%? A previous study indicates that the proportion of households with two computers is 23%. Group of answer choicesA city has 4 voting districts. Records from previous years show the proportion of registered voters that voted in previous elections for each district. A political analyst wants to see if those proportions have changed for this year's upcoming elections. The political analyst randomly samples 123 registered voters and asks them which district they live in and if they have voted yet. Ho: PA 0.1; PB = 0.5; Pc = 0.3; PD = 0.1 Test the claim that there is a difference in the proportions using a a= 0.1. Round all answers to at least 4 decimal places. a. Complete the table.

- In politics, marketing, etc we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error- the largest (reasonable) error that the poll can have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely between 68% and 76% In a made up poll, the proportion of people who like dark chocolate more than milk chocolate was 39% with a margin of error of 2.2%. Describe the conclusion about p using an absolute value equality. I came up with .368 <= p <= .412 but I don't think it's right, please show steps so I can see where I went wrong!The city of Raleigh has 10200 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 400 randomly selected registered voters was conducted. 197 said they'd vote for Brown, 176 said they'd vote for Feliz, and 27 were undecided.Give the sample statistic for the proportion of voters surveyed who said they'd vote for Brown.
