Answer:
100% chance of this happening.
Step-by-step explanation:
The chances of this happening = 100% because all the numbers are greater than 0.
32/68 can be reduced to 8/17.
Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
OR u can use , z-tests are used when we have large sample sizes (n > 30), whereas t-tests are most helpful with a smaller sample size (n < 30). Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.

Step-by-step explanation:
5y + x - y; use x = 1, and y = 6
You plug the numbers in.
5(6) + 1 - 6
30+1-6

The formula for length of an arc on a circle is given by the formula:
,
where 'r' is the radius of the circle and 'x' is the measure of the central angle of the arc.
We have to determine the value of radius 'r'.
Since,
By Cross multiplication, we get
Therefore, the radius 'r' is given by .
Option 4 is the correct answer.
