Answer:
Step-by-step explanation:
Given that researchers are studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15.
a) The population is the children between the ages of 5 and 15 in general
D. All children between the ages of 5 and 15
b) Sample is
D. 160 children between the ages of 5 and 15
c) Yes becauB. If the sample is randomly selected and representative of the entire population, then the results can be generalized to the target population. Furthermore, since this study is experimental, the findings can be used to infer causal relationships.se randomly selected and also sample size is above 30
I need to see the graphs... can you add them ?
Answer:
(a) 3
Step-by-step explanation:
Calculate the slope m of the line given using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0,3) and (x₂, y₂ ) = (3, 2)
m = 
= - 
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 3 → (a)
Answer: The lower quartile is 6
Step-by-step explanation: To find the lower quartile of a set of data, we can find the median of the data and then find the median of the first half. This strategy is similar to dividing a cake into halves, and then dividing one of the halves in half so that you end up with a quarter of the cake.
