Answer:
C. -0.68427
Step-by-step explanation:
Enter the data into a graphing calculator.
First decide which is the independent and which is the dependent variable. Since the value of the stock depends on the day, value will be dependent and day will be independent.
This means that the days will be entered into the first list and the values will be entered into the second list.
Entering these and running the linear regression, we find the r-value to be -0.68427
.
As the sine rule states,
A/sina = B/sinb = C/sinc .
in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.
there are:
side a, with angle â .
side b, with angle b.
so the answer is C.
if you input these into the sine rule, it would be:
a/ sin a = b/sin b
Answer:
(a) Confirmation bias
(b) Likely less than actual proportion of families who support the proposal
(c) Random sample
(d) Nonresponse bias
Step-by-step explanation:
In confirmation bias, the researcher already has and intends to prove an assumption about the effect the of a treatment before carrying out the survey, such that the survey or research is tries to dictate to the participants in the survey about the desired outcome
In the question, the belief of the researcher is expressed to the participants in a form of brief at the start of the survey which is attempting to influence the responses to the survey, such that the actual result should be less than what was observed.
