Answer:
D
Step-by-step explanation:
Sample space = {H1,H2, H3, H4, H5, H6 , T1, T2, T3, T4, T5, T6}
So, (H, 6) is an element in the sample space
To do this you would divide the weight by the number of buckets to get the unit rate. Unit rate is how much for 1.
Answer:
Step-by-step explanation:
Equations:
x + y = 7
x - y = 3
Add and solve for "x":
2x = 10
x = 5
Solve for "y":
x + y = 7
5 + y = 7
y = 2
Answer:
Correct option is (a).
Step-by-step explanation:
The dependent <em>t</em>-test (also known as the paired <em>t</em>-test or matched-samples <em>t</em>-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.
We use the paired <em>t</em>-test if we have two measurements on the same item, person or thing. We should also use this test if we have two items that are being measured with a unique condition.
For instance, an experimenter tests the effect of a medicine on a group of patients before and after giving the doses.
Or in case of testing the level of reading comprehension of students before and after the speed-reading class we use t-test for dependent means.
The assumptions of paired <em>t</em>-test are:
- The dependent variable that is tested should be continuous
- The observations are independent
- The dependent variable is normally distributed
- There should not be any outliers.
Since the data consists of matched pair, both the samples must be of the same size.
Thus, the correct option is (a).
