Answer:
No, the weight loss program doesn't have statistical significance.
Step-by-step explanation:
We are given that in a study of a weight loss program, 7 subjects lost an average of 41 lbs.
It is found that there is about a 40% chance of getting such results with a diet that has no effect.
Firstly, statistical significance means that the event is sure to be happen and there is a proper statistical calculation behind it.
But here it is stated that there is a 40% chance of getting such results with a diet that has no effect which means that the event is unlikely to happen by chance and it is just a prediction so, the weight loss program is not statistically significant.
Now, practically significant means that there is a large difference in the subjects being tested.
Here, the weight loss program is considered to be practically significant because there is a large amount of weight loss of 43 lbs of the subjects which is a large amount.
Answer:
1/6
Step-by-step explanation:
Let E1 and E2 represent the empty cans and W1 and W2 be the cans filled with water.
S = { E1E2, E1W2,E2W2, E1W1, E2W1, W1W2 }
By merely guessing, the events are equally likely. Since there are 6 possible outcomes,
probability = 1/6
Answer:
x = 3
y = -2
Step-by-step explanation:
x - 2y = 7
y = -x + 1
x - 2y = 7
x - 2 ( -x + 1 ) = 7
3x - 2 = 7
3x = 9
x = 3
y = -x + 1
y = -3 + 1
y = -2
