Two opinion polls, seeking information about the proportion of voterssupporting a certain political party, were carried out.a) For the first poll, one thousand randomly chosen people were in-terviewed and 368 of them said they intended to support the party.Calculate an approximate 95% confidence interval for the popula-tion proportion supporting the party. Give your answer to 3 deci-mal places.b) The result of the second poll was reported in a newspaper. Thereport said that support for the party was"between 33% and 37%,based on a sample of 3774 people".If we express this information as an approximate k% confidenceinterval, calculate the value of k (to the nearest integer).

It is given that First poll: Favourable cases, X = 368 Sample size, n = 1000 Second poll: kth%…

Answered: a) For the first poll, one thousand…

1. A company surveyed its employees to determine what the new daily meal allotment dollar amount should be. Of the 159 employees, 94 responded. Pat’s supervisor asked what the recommended dollar amount should be. Pat could take the mean of the 94 responses or calculate a confidence interval about the mean using those 94 responses. Which action of the two (don’t go outside these choices) would give the supervisor a better idea of what the true mean is, and why?
You recently sent out a survey to determine if the percentage of adults who use social media has changed from 60%, which was the percentage of adults who used social media five years ago. Of the 2930 people who responded to survey, 1645 stated that they currently use social media. a) Use the data from this survey to construct a 94% confidence interval estimate of the proportion of adults who use soclal media. Record the result below in the form of (#, #). Round your final answer to four decimal places. b) Can you conclude that the percentage of adults who use social media has changed? Explain. O Yes, because the proportion of adults who used social media five years ago is inside of the confidence interval. O Yes, because the proportion of adults who used social media five years ago is not inside the confidence interval. O No, because the proportion of adults who used soclal media five years ago is Inside the confidence interval. O No, because the proportion of adults who used social…
