Answer:
95% Confidence Interval = (611.81 ppm, 696.51 ppm)
Step-by-step explanation:
The formula for Confidence Interval is given as:
Confidence Interval = Mean ± z × s /√n
Mean = the sample mean/average = 654.16
s = the sample standard deviation = 164.55
z = z score of 95% confidence interval = 1.96
Confidence Interval =
654.16 ± 1.96 × 164.55/√58
= 654.16 ± 42.348
Hence,
654.16 - 42.348
= 611.812
Approximately to two decimal places = 611.81 ppm
654.16 + 42.348
= 696.508
Approximately to two decimal places = 696.51 ppm
Therefore, the 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected is (611.81 ppm, 696.51 ppm).
Answer:
∠J = 180° - 65° - 40° = 75°
Answer:
-7y
Step-by-step explanation:
-2y-7y=
-9y+8y=
-y+y=
0-7y=
-7y
Assuming those lines are parallel, then this means the alternate interior angles are the same measure
3x-26 = 2x
3x-26+26 = 2x+26 ... adding 26 to both sides
3x = 2x+26
3x-2x = 2x+26-2x ... subtracting 2x from both sides
3x-2x = 26
<h3>x = 26 is the answer</h3>
