Question
To Explain:the expected the mean, median,standard deviation and IQR to change.

1,4, 1:5, 1.7, 19,29) 2.3,9°6, 2.6, 9.6, 9.8, 0:9, 3'1, 3.2,913, 3.3, 3.4, 4.9.4.4, 45.
Total number of values is odd so median is the $$10^{th}$$ value that is 2.8%.
$$Mean=\frac{61.4\%-7.5\%}{19}=2.8\%$$
So new mean is equal to 2.8%
Standard deviation decreases. Las Vegas job growth percentage works as an outlier in the distribution so omitting Las Vegas decreases standard deviation also.
Las Vegas value is last in order data set so omitting it does not change IQR.

Explain which measure of center best describes a typical wage at this company:the mean or the median.
A meteorologist preparing a talk about global warming compiled a list of weekly low temperatures (in degree s Fahrenheit) he observed at his southern Florida home last year. The coldest temperature for any week was 36°F, but he inadvertently recorded the Celsius value of 2°. Assuming that he correctly listed all the other temperatures, explain how this error will affect these summary statistics:
a) measures of center: mean and median. b) measures of spread: range, IQR, and standard deviation.

American automobiles produced in 2012 and classified as “large”; had a mean fuel economy of 19.6 miles per gallon with a standard deviation of 3.36 miles per gallon. A particular model on this list was rated at 23 miles per gallon, giving it a z-score of about 1.01. Which statement is true based on this information?

A) Because the standard deviation is small compared to the mean, a Normal model is appropriate and we can say that about $$84.4\%$$ of of large automobiles have a fuel economy of 23 miles per gallon or less.
