In June 2009, a Harris Interactive poll surveyed individuals about the influence of advertising on their purchasing decisions. Among those aged 18 to 34, 44% believed advertisements were influential, compared to 36% of those aged 35 to 44. The poll included 655 people from the 18 to 34 age group and 430 from the 35 to 44 age group. A 98% confidence interval is to be calculated for the difference in population proportions between these age groups.Let \( p_1 \) represent the proportion of adults aged 18 to 34 who view advertisements as influential, and \( p_2 \) represent the proportion of adults aged 35 to 44 with the same view. You are required to determine \( \, p_1 - p_2 \, \) and round your answers to three decimal places.The image contains placeholders represented as:\[ \text{[info icon]} < p_1 - p_2 < \text{[info icon]} \]These placeholders are meant to input values for the lower and upper bounds of the confidence interval.

The value of z at 98% confidnce level is 2.326, which can be obtained by using the standard normal…

A researcher was interested in finding out whether students’ sense of belonging in a course differed between students attending classes on campus and students attending classes on Zoom. They recruited five students attending classes on campus and five students attending classes on Zoom to test this. Students were asked to complete a survey measuring how much they felt like they belonged in the course. The scale ranged from 0 (not at all) to 10 (very much). Students’ data, which were non-normal, are provided below.
