A sample proportion of 0.78 is found. To determine the margin of error for this statistic, a simulation of 100 trials is run, each with a sample size of 50 and a point estimate of 0.78. The minimum sample proportion from the simulation is 0.62, and the maximum sample proportion from the simulation is 0.80. The margin of error of the population proportion is found using half the range. What is the interval estimate of the true population proportion?
A. (0.72, 0.84)
B. (0.64, 0.92)
C. (0.74, 0.82)
D. [tex]$(0.69,0.87)$[/tex]
Answer (2)
Well, one part is 3800 so the remaining 17-2=15 parts was 57000 people.
In a crowd of 7,600 people with a ratio of laughers to stolid individuals as 2 to 17, there are 800 laughers and 6,800 who did not laugh. Therefore, 6,800 people did not laugh. This is calculated by understanding the ratio and dividing the total number of people into respective parts.
