Answer:

Step-by-step explanation:
Given
See comment for data
Required
The lower limit 94% confidence interval
First, calculate the mean




Next, calculate the standard deviation using:

So, we have:




For 94% interval, the z score is

So, the margin of error (E) is:




The confidence interval of the true mean is:

The lower limit (L) is:



and the upper limit (U) is



<em>Answer:</em>
<em>20</em>
<em>Step-by-step explanation:</em>
<em>160% ............ 32</em>
<em>100% .................x</em>
<em>x = 100*32/160 = 3200/160 = 20</em>

Answer:
Step-by-step explanation:
Answer:
y=2x+17
Step-by-step explanation:
y-y1=m(x-x1)
y-1=2(x-(-8))
y-1=2(x+8)
y=2x+16+1
y=2x+17
7X +3 equals 17: solve for x
Help! X= 2
