Answer:
<h3>
a₇₅ = 606</h3>
Step-by-step explanation:

Answer:
critical value = 1.645
The 90% confidence interval = ( -22.62, -17.58)
Step-by-step explanation:
Given that:
the sample size
= 178
the sample size
= 226
the sample mean
= 54.4
the sample mean
= 74.5
population standard deviation
= 18.58
population standard deviation
= 9.52
level of significance ∝ = 1 - 0.90 = 0.10
The critical value for
is 1.645
For the construction of our confidence interval, we use 90% since that is used to find the critical value.
∴
The margin of error = 



2.52
The lower limit = 
= ( 54.4-74.5) - (2.52)
= -20.1 - 2.52
= -22.62
The upper limit = 
= ( 54.4-74.5) + (2.52)
= -20.1 + 2.52
= -17.58
The 90% confidence interval = ( -22.62, -17.58)
everyone will get 2 burgers i got this answer by multiplying 8 and 6 and then i divided it by 24 and i got 2
hope it helps
You can think of midpoint as being an average.
Add the values and divide by 2.
(x1 + x2)/2, (y1 + y2)/2
(2 + 6)/2, (3 + 11)/2
(4,7) would be the midpoint
