Answer:
b. Square root of the variance
Step-by-step explanation:
The standard deviation measure how scattered the data of the set is, in other words, measure the dispersion. A low value is found when the points are close to the mean, and when the value is high the data uses a wider range of values. To calculate its value, the simple way, you need the variance because the standard deviation is the square root of the variance.
Answer:
I'm assuming you want me to do 18-23? Okay:
Step-by-step explanation:
<u>18) </u>8.6(10^−4)+6.7(10^−5)
=0.000927 --> 9.27 × 10^-4
<u>19)</u> 3.5(10^3)−9(10^1)
=3410 --> 3.41 × 10^3
<u>20)</u> 5.6(10^4)(4.5(10^6))
=252000000000 --> 2.52 × 10^11
<u>21)</u> 7.6(10^−7)(8.9(10^−2))
=0 --> 0
<u>22)</u> 3.9(10^−12)/4(10^4)
=0 --> 0
<u>23)</u> 1.75(10^5)/5(10^−3)
=35000000 --> 3.5 × 10^7

Answer:
The correct option is D
Step-by-step explanation:
The correct option is D
The regression of binary variable interaction enables one of binary independent variables to be modified based on value of other binary variable.
In regression, whenever the impact of an independent variable on the dependent variable reforms, based on a value(s) of one or more than one independent variables, an interaction impact exists.
