Answer:
1.703
Step-by-step explanation:
The reason we try to find t score is because the sample size is below 30, meaning the sample size is small
Hence:
Step 1
We find the degree of freedom
The Degrees of freedom = Number of samples - 1
The random number of samples = 28
= 28 - 1
= 27
Step 2
Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27
90% confidence interval =
10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail
Hence: t90 = 1.703
Answer:

Step-by-step explanation:
The
-intercept of a line is the
value when
. In the equation
, we can solve for its equation when we plug in
.
Solving for
when
:
.
So the
-intercept of the equation
is
.
To find what equation has the same
-intercept, we can do the same process for each equations given by the choices. However, I can see that the equation,
, has the
-intercept. If in doubt, you can check for the solution below or solve each equations for yourself.
Solving for
when
:

Hey!
NO IT IS NOT A STATISTICAL QUESTION!
Step-by-step explanation:
This is because you are including ONLY YOU...this wont work as statistics take data from a COLLECTION of people or things!
