28 lb. 6 oz. − 11 lb. 5 oz. =

17lbs. and 1oz.

Step-by-step explanation:

First I would separate the oz. and the lbs. and subtract them separately.

28lbs. - 11lbs., and 6oz. - 5oz.

then I would subtract;

28lbs. - 11lbs.= 17lbs.

6oz. - 5oz.= 1oz.

So your 2 answers would be 17lbs. and 1oz.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
