I ask the question again here (in bartleby) , because my teacher said it was wrong (the answer I got from the other bartleby expert). It´s ok!! just please read the instructions and data carefully.   (answer the question in the image)

Consider the following ordered data. 4   7   7   8   9   9   10   11   12 Find the low, Q1, median, Q3, and high Find the interquartile range

The histogram (click the attacthed photo to view) shows the distribution of hurricanes that have hit a country from 1851 through​ 2015, where 1 is the weakest level and 5 is the strongest level.   A) The mean is? B) The variance is? C)The standard deviation is?

The sample mean is often used as an estimator of the population mean because of its desirable properties, including: a. unbiasedness, consistency and efficiency Ob.consistency and minimum sampling error only Oc unbiasedness and consistency only Od. unbiasedness and efficiency only Oe. unbiasedness, consistency and minimum sampling error
