A study was conducted to find out if a new exercise program was more effective than an old one at improving cardiovascular fitne
WITCHER [35]

Answer: (B)

Step-by-step explanation:

An independent sample test compares two sample means in order to determine the statistical significance of the difference between their population means.

The independent sample test would be the best hypothesis test for this study because:

1. There was a random samples of data from the population

2. There was no relationship between the subjects in each sample. That is;

- subjects in the first group were not also in the second group

- subjects in the first group did not influence subjects in the second group and vice versa.

3. There was independence of observations in this study. Each subject in each group was separately observed and each subject has a given fitness performance score.

4. There are values on both the dependent and independent variables.

- the dependent variable is FITNESS PERFORMANCE and for each subject, it is dependent on either the OLD EXERCISE PROGRAM or the NEW EXERCISE PROGRAM.

5. Our dependent variable her is a continuous variable as we see from the range of fitness scores. The lowest score is 19 and the highest score is 73. This shows that the variable is continuous. All the other scores fall in between.

6. Our independent variable is a categorical variable. Categorized into OLD EXERCISE PROGRAM and NEW EXERCISE PROGRAM.

Choose all the expressions that are equal to 0.7 × 0.41.
dlinn [17]

Answer:

None of the expressions is equal to 0.7 x 0.41.

Step-by-step explanation:

Given that 0.7 x 0.41 is equal to 0.287, to determine which options are equal to said operation, the calculations set out for each of them must be performed:

A. 7,100 × 41100 = 291,810,000

B. 710 × 41100 = 29,181,000

C. 7100 × 4110 = 29,181,000

D. 710 × 4110 = 2,918,100

E. 70100 × 41100 = 2,918,100,000

Therefore, looking at all the results produced by the predisposed calculations, it is evident that none of the expressions is equal to 0.7 x 0.41.
