Life rating in Greece. Greece faced a severe economic crisis since the end of 2009. Suppose a Gallup poll surveyed 1,000 randomly sampled Greeks in 2011 and found that 26% of them said they would rate their lives poorly enough to be considered "suffering." Round all answers to two decimal places.

1. What is the population parameter of interest?
A. The 25% of Greeks in the sample who believe they are suffering.
B. The score on the survey that corresponds to suffering.
C. The actual proportion of Greeks who believe they are suffering.
D. All the people who live in Greece.

2. What is the value of the point estimate of this parameter?

3. Construct a 95% confidence interval for the proportion of Greeks who are "suffering." ( , )

4. If we decided to use a higher confidence level, the confidence interval would be:
A. narrower
B. wider
C. stay the same

5. If we used the same confidence level with a larger sample, the confidence interval would be:
A. wider
B. narrower
C. stay the same

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
