104 108 112 116 120 124 128 132Number of successesA company wants to know if more than 80% of people approve of their new advertising campaign. Arandom sample of 150 likely voters is taken, and 124 of them (83%) say that they support theproposition. In order to conduct a statistical analysis, the One Proportion applet was used to see ifthe candidate's claim is plausible. Use the dot plot generated by the applet (pictured above) toanswer the questions.a) There are 100 dots in the simulated distribution. What does each dot represent?O The number of people who support the ad campaign in a sample of 100 people, if we assumethat 83% of the population supports the ad campaign.The number of people who support the ad campaign in a sample of 150 people, if we assumethat 83% of the population supports the proposition.O The number of people who support the ad campaign in a sample of 100 people, if we don'tknow the percent of people in the population who support the ad campaign.The number of people who support the ad campaign in a sample of 150 people, if we assumethat 80% of the population supports the the ad campaign. b) If we switched the applet to display "Proportion of successes" then what value would thedistribution be centered at?O 0.8150130O 0.87c) Is the observed statistic "usual/expected" or is it "unusual/unexpected" in this simulateddistribution of sample statistics?O Usual/expected because 80% is pretty close to 83%.Unusual/unexpected because it is in the tail of the distribution.O Usual/expected in this distribution.d) Which of the following conclusions is the most accurate to make based on our observed statistic?Because our statistic is unusual/unexpected, we have strong evidence that the ad campaignhas more than 80% support in the population.O We conclude that the ad campaign has 80% support in the population.We conclude that the proposition has 83% support in the population.Because our statistic is usual/expected, it is plausible that the ad campaign has 80% supportin the population.Question Help: Video> Next Question
