Question
budgel is recorded of 10 hens. The sample mean of the number of eggs times, and build a new distribution of sample means. How will distribution compare to the variability of the original distribution?aility e thi p is recorded, and (d) Suppose the researchers' eat t the variability of h n hish school iunions cn itter users and news, Part I. A poll conducted in 2013 found that 52% of US ata Twitter users get at least some news on Twitter.2. The standard error for this estimate was 2.4%, and a normal distribution may be used to rnodel the sample proportion. Construct a 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter, and interpret the confidence interval in context.Explanation / Answer
Result:
d).
Variability of the new distribution is smaller than old one.
standard error = sd/sqrt(n)
n=1000
standard deviation of the new distribution = sd/sqrt(1000) = 0.0316 of the old sd.
5.8
P=52% or P=0.52
Standard error = 2.4% or 0.024
Z value for 99% level =2.576
99% CI = p±z*se = 0.52±2.576*0.024
=(0.458176, ,0.581824)
