Question

determine whether the results below appear to have statistical significance, and also determine whether the results have practical significance. in a study of a weight loss program, 5 subjects lost an average of 43 lbs. methods of statistics can be used to show that if this diet had no effect, there is a 23% chance of getting these results by random chance. does the weight loss program have statistical significance? a. yes, the program is statistically significant because the results are likely to occur by chance. b. no, the program is not statistically significant because the results are unlikely to occur by chance. c. no, the program is not statistically significant because the results are likely to occur by chance. d. yes, the program is statistically significant because the results are unlikely to occur by chance.

Explanation:

In statistics, a result is considered statistically significant if the probability of it occurring by chance is low. Here, there is a 23% chance of getting these results by random chance. Usually, a significance level of 5% or less is used. Since 23% > 5%, the results are likely to occur by chance, so the program is not statistically significant.

Answer:

C. No, the program is not statistically significant because the results are likely to occur by chance.
