Answer:
t = -1.428
Step-by-step explanation:
Average blood pressure among people with high responsibility jobs = u = 140 mm
Number of people sampled for the study = n = 51
Average blood pressure of the sample = x = 139 mm
Standard deviation of the sample = s = 5 mm
The claim is that practicing yoga decreases the blood pressure. So we have to test that after practicing yoga, the average blood pressure will be lesser than 140. Based on this we can formulate the null and alternate hypothesis as:
Null Hypothesis:
Alternate Hypothesis:
Since population standard deviation is not known, we cannot use z-distribution for this test. We are given the value of sample standard deviation, so t-test will be used for this case.
Test statistic is calculated as:
Using the values in this formula gives us:
Therefore, the value of test statistic is -1.428
Answer:
A - They Have Too Much Caramel
Step-by-step explanation:
Ari likes 3 oz caramel for 5 scoops ice cream.
Freeze Zone makes 6 oz caramel with 8 scoops of ice cream.
Divide both amounts of Freeze Zone by 2.
6 oz caramel for 8 scoops of ice cream is the same ratio as
3 oz caramel for 4 scoops of ice cream.
Since Ari likes 3 oz caramel for 5 scoops ice cream,
he will think it's too much caramel for the ice cream.
Answer: A - They Have Too Much Caramel
So the length of the arc is given by: l = r*theta, here theta is the intercepted angle in unit radian
So, 80 degrees = 80/360 * 2pi = 4/9 * pi
So l = r * (4/9 * pi), the constant ratio is 4/9 * pi
Answer:
No, but i would like to know who they are
Step-by-step explanation:
No, because if you divide 23 / 4, you get 5.75. You can't get 0.75th of a kid. So it is not reasonable, because it is a decimal, and not a whole number.
Hope this helped! ☺♥
