The phrase best describes the range of the function h(x) is option A: all real numbers.
<h3>What is a range of a function?</h3>
The range is the set of all values which the given function can output.
A step function h(x) is represented by y = -2|x|.
The mode of x gives the real number every time by putting the values.

Answer:
mean lean body mass of the lean monkeys = 8.4kg
mean lean body mass of the obese monkeys = 10.4kg
Step-by-step explanation:
a) Mean = Sum of Body mass/number of body mass
For lean monkeys, mean = (6+7.5+9.2+9.7+9.1+9.1)/6
Mean = 50.6/6
Mean = 8.4
b)
for obese monkeys, mean = (8+9.1+10.3+12+11.9+11.2)/6
Mean = 62.5/6
Mean = 10.4

Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05
