Below you’ll find summary statistics and a frequency distribution about apartments located in Vienna,Austria. The variable in particular this information is for contains the “# of square meters in the kitchenper apartment.” I have limited the sample to where only a specific district in the city is shown.Summary statistics, using the observations 401 – 602for the variable 'kitchen_sq' (202 valid observations)Mean 3.5347Median 0.00000Minimum 0.00000Maximum 120.00Standard deviation 9.2533C.V. 2.6179Skewness 9.9905Ex. kurtosis 122.565% percentile 0.0000095% percentile 9.8500Interquartile range 8.000Missing obs. 0a. Using the information as furnished above, construct a 95% confidence interval for the truepopulation mean of kitchen square meters in this district in Vienna. Show and describe yourwork. b. Explain, in plain English, what a confidence interval is. Use the numbers used above in theresults above to frame the discussion.

Question 2 of 10 To estimate the mean height of female high school juniors, you take a random sample of 30 female students and get these results (in inches): 72, 51, 67, 68, 61, 69, 58, 56, 60, 56 66, 61, 60, 59, 59, 54, 58, 53, 68, 63 57, 62, 63, 64, 56, 62, 58, 67, 57, 70 If the o is 5.3, based on past research, and you want to construct a 97% confidence interval using (estimate) ± (margin of error)= (estimate) ± z* what's your value for z*? O A. 1.645 В. 2.17 О с. 1.96 D. 2.576 O E. 1.88

When taking a sample for research we need to be mindful of the Central Limit Theorem which assumes the population distribution is called?
