Answer to Problem 26E
Median would be affected marginally.
The mean would be skewed download.
Explanation of Solution
Median would be affected marginally.
The mean would be skewed download.
The median would not be change. The lowest temperature was the lowest temperature already, and it simply got lower. Its placement in the data was always 1st, when ordered, so the median does not change. The mean, however, is the average of all values. Replacing one value with a much smaller value will cause the mean to decrease.

Expert Solution
Answer to Problem 26E
The range will increase significantly
The IQR will not change.
The standard deviation will increase significantly.
Explanation of Solution
The range will increase significantly (by 34, to be exact).
The IQR will not change.
The standard deviation will increase significantly.
The range is the highest number minus the lowest. If the lowest number decreases significantly, the range would increase by the change. The IQR only counts the first and third
