Answer:
Step-by-step explanation:
Given that a study was conducted to find out if a new exercise program was more effective than an old one at improving cardiovascular fitness.
Subjects were randomly selected to participate and then randomly assigned to one of the two programs. After six months of exercising, they were given a score based on their fitness performance. Scores ranged from 19 to 73, with higher scores indicating higher performance.
Here there are two groups one for each program. After recording the scores groupwise, mean, std deviation of each group to be calculated.
Then independent sample test (option B) to be done.
Paired data set is not right because same person cannot be in two programs.
Here proportion is not recorded so D is wrong. Since variance is not checked anova is not right. Independence is not checked so E is wrong. Regression is wrong because there is no estimate for regression line here
B) is right.
Answer is b hope this helps
Answer:
-3/17
Step-by-step explanation:
(7,1) and (-10,4)
slope formula: m = (y₂ - y₁) / (x₂ - x₁)
plug in data: m = (4 - 1) / (-10 - 7)
solve: 3 / -17
simplify: -3/17 (written as a fraction)
Your answer would be 31.5 (so 32 when rounded up)
For triangles you basically multiply them together, and the divide your answer by two.
A= 1/2 b x h
A= 1/2 7 x 9
A= 1/2 63
A= 31.5 (rounded up to 32)

82.4+108.6=191 and 12052.1 divided by 191=63.1
So the answer is 63.1
