Answer:
y+2-x=0
Step-by-step explanation:
Here,
(-3,-5)=(x1,y1)
(3,1)=(x2,y2)
Slope(m)=y2-y1/x2-x1
=1-(-5)/3-(-3)
=1+5/3+3
=6/6
=1
Mid point=(x1+x2/2 , y1+y2/2)
=(-3+3/2 , -5+1/2)
=(0/2 , -4/2)
=(0 , -2)
Now, (0,-2)=(x1,y1)
Equation:
y-y1=m(x-x1)
y+2=1(x-0)
y+2=1x
y+2-x=0 is the required equation.

Geez that is real complicated sorry I’m not sure just go with your gut
Answer:
Approximately 5 intervals will not capture the true mean hour of sleep freshman get at night.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean implies that there is a (1 - α) probability that the true value of the mean is included in the interval.
Or, the (1 - α)% confidence interval for the mean implies that there is (1 - α)% confidence or certainty that the true mean value is contained in the interval.
And, if 100 such (1 - α)% confidence interval for the mean are computed then 95 of these 100 interval will consist of the true mean value.
In this case it is provided that 100 researchers estimate the population mean hour of sleep freshman get at night, and each one construct a 95% confidence interval for the mean.
Then approximately 95 of these 100 confidence intervals will capture the true mean hour of sleep freshman get at night. And approximately 5 intervals will not capture the true mean hour of sleep freshman get at night.
