Answer as a fraction = 2/3
Answer in decimal form = 0.667 (approximate)
=======================================================
Explanation:
The first thing we need is to find the mean. Add up the values to get 3+3+4+5+5+4 = 24. Then divide by n = 6 since there are 6 values.
24/n = 24/6 = 4
The mean is 4
Now subtract the mean from each value
- 3-4 = -1
- 3-4 = -1
- 4-4 = 0
- 5-4 = 1
- 5-4 = 1
- 4-4 = 0
Apply absolute value to each result so that the difference is not negative.
We get this new list: {1, 1, 0, 1, 1, 0}
Now compute the mean of that new list to get the final answer
1+1+0+1+1+0 = 4
4/n = 4/6 = 2/3 = 0.667 approximately
Answer:
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
Step-by-step explanation:
To find the interval, we can just make the conversion of the values from pounds to kilograms.
Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.
Confidence interval: (102.3 pounds, 106.5 pounds).
102.3 pounds = 102.3/2.2 = 46.5 kilograms
106.5 pounds = 106.5/2.2 = 48.41 kilograms
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
B. might be 4/x=3/4. I'm no mathematician, but if it's wrong, blame my teacher. d would probably be something. I'm no good with numbers.
