Since this is a cube, we can use the volume formula for a cube.
s is the lenght of one of the edges of the cube.
The edge of the cube has a length of 4.2 in. Let's plug it into the formula.
That's your answer. I hope this helps! :)
1. To calculate the mean, we first total the number of hours: The 20 students' total number of study hours
is 118.5 hours.
2. We divide by the number of samples to find the mean: <span>The sample mean is 5.93.</span>
3. Next, we find the SD: <span>Calculate the standard deviation.</span>
4. Then we divide SD by the number of samples to get the standard error: the standard error of the mean of the sample is 0.45.
5. Since for a 95% CI, the corresponding z-score is 1.96 ~ 2, we use the formula for CI: mean +/- z*SE, which is: The range in which 95% of the sample
mean occurs is 5.93 + 2 × 0.45 = 6.83 hours and 5.93 − 2 × 0.45 = 5.03
hours.
6. Finally: The range in which
95% of the sample mean occurs is (5.03, 6.83).
Answer:
561-566 and the other one I was talking to about this one you had matching the name and I was wondering what the price
Ok, if you want to find out the range of the hours they play, here it is:
Since the number of hours for Bonnie are 4, 5, 4, 3, 3, 5, the range should be 3, 4, 5, which makes the range 3.
Since the number of hours for Adele are 5, 5, 9, 8, 8, 7, the range should be 5, 7, 8, 9, which makes the range 4.
Which means Adele's range is bigger than Bonnie's!
