The research question asks whether the number of people who support a minimum wage has changed. It is stated that 65% of people support a higher minimum wage. A sample of 930 people is collected, and out of these, 635 of them represent the percentage that supports a higher minimum wage.
To determine if the number of people who support a minimum wage has changed, we need to compare the percentage in the sample to the known percentage.
In the sample of 930 people, 635 of them support a higher minimum wage. To find the percentage, we divide 635 by 930 and multiply by 100:
\(\frac{635}{930} \times 100 = 68.28\%\)
The percentage in the sample is approximately 68.28%, which is higher than the known percentage of 65%. This suggests that there may have been a change in the number of people who support a minimum wage. However, it's important to note that this conclusion is based on the sample data and may not necessarily reflect the entire population.
In summary, based on the sample data, the number of people who support a minimum wage appears to have increased. However, further analysis and consideration of the entire population is needed to draw a definitive conclusion.
