Answer:
Step-by-step explanation:
weights of parakeet = 240 g
Weight of cat = 3.1 kg = 3.1 * 1000 = 3100.0 g = 3100 g
difference = 3100 -240 = 2860 g
Answer:
29000, with the margin of error of ±5000
Step-by-step explanation:
Margin of error is the amount of error that can be caused due to variation, change of circumstances or any miscalculation.
In given case value of college student's debt can be between
24000 and 34000
Finding mid-point
(24000+34000)/2
29000
Now finding deviation of 29000 from 24000 and 34000
24000-29000= -5000
34000-29000= 5000
Hence
29000, with the margin of error of ±5000 !
Answer:
a = -29
Step-by-step explanation:

1st step is to multiply -2 on both sides
Answer:
a) 66.1 < μ < 82.7
b) 71.9 < μ < 97.7
c) D. No, because the two confidence intervals overlap, we cannot conclude that the two population means are different.
Step-by-step explanation:
Confidence interval is given by the formula
M±t×(
) where
- M is the sample mean
- t is the corresponding t value for 95 confidence level
- s is the sample standard deviation
- N is the sample size
<u>a. Construct a 95% confidence interval estimate of the mean pulse rate for males.</u>
For men:
M=74.4 t=2.262 s=11.6207 N=10 then confidence interval is:
74.4±2.262×(
) ≈ 74.4±8.3
<u>b. Construct a 95% confidence interval estimate of the mean pulse rate for females.</u>
For women:
M=84.8 t=2.262 s=18.0488 N=10 then confidence interval is:
84.8±2.262×(
) ≈ 84.8±12.9
<u>c. Compare the preceding results. Can we conclude that the population means for males and females are different?</u>
Difference of Population means for males and females are not statistically significant, since confidence intervals overlap.

<h3>I'll teach you how to solve 2x=10</h3>
------------------------------------------------
2x=10
Divide both sides by 2:
2x/2 = 10/2
Simplify:
x=5
Your Answer Is x=5
