Answer:
95% (two-sided) confidence interval for the proportion of all dies that pass the probe is between 0.470 and 0.574
Step-by-step explanation:
Confidence interval can be calculated as p±ME where
- p is the sample proportion of dies that pass the probe
- ME is the margin of error
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion (
)
- N is the sample size (356)
Using the numbers in the formula we get
ME=
≈0.052
then the 95% confidence interval would be 0.522±0.052
Answer:
Approximately mMK is 53 degrees
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree
Approximately, L = 53 degrees
so now, we want to get the arc length MK
We are to use the angle-arc relationship here
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees
2 boxes per minute. 1/3 of a minute, is 20 seconds. so 2/3 of a box is made every 20 sec. Now, if there are 3, 20 sec periods in a minute, so multiply 2/3 (0.666667) boxes by 3 =2 boxes
