The mean value of land and buildings per acre from a sample of farms is $1300, with a standard deviation of $200. the data set has a bell-shaped distribution. using the empirical rule, determine which of the following farms, whose land and building values per acre are given, are unusual (more than two standard deviations from the mean). are any of the data values very unusual (more than three standard deviations from the mean)? $1616 $1774 $1309 $606 $1470 $1542

Values are unusual : $1774 and $606

Very unusual value =   $606

Step-by-step explanation:

According to the empirical rule, when data is normally distributed (bell-shaped) then the values that are two standard deviations from the mean are unusual.

Given data: $1616 $1774 $1309 $606 $1470 $1542

Mean :  and Standard deviation:

The range of the values lies within from mean .

The values are unusual (i.e. more than two standard deviations from the mean) = $1774 and $606

The range of the values lies within from mean .

The values are very unusual (i.e. more than three standard deviations from the mean) = $606

answer: 12

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
