Bonferroni's method ensures that the family-wise error rate is less than or equal to the design level such as 0.05 after all possible pairs-wise comparisons have been made. Three groups have 3 possible pairs-wise comparisons. Four groups have 6 possible pairs-wise comparisons.
Please answer following questions 26-29 based on this method.

A study has three groups. Given an overall design error rate 0.05, a pairs-wise comparison can be claimed statistically significant difference when the p-value less than 0.05/3=0.017
Option: 0.017
A study has four groups. Given an overall design error rate 0.05, a pairs-wise comparison can be claimed statistically significant difference when the p-value less than 0.05/6=0.008
Option: 0.008
A study has three groups. An investigator wants to claim a statistically significant difference if a pairs-wise comparison p-value less 0.05. The overall design error rate for this study could be as large as 3*0.05=0.15.
Option: 0.15
A study has four groups. An investigator wants to claim a statistically significant difference if a pairs-wise comparison p-value less 0.05. The overall design error rate for this study could be as large as 6*0.05=0.30.
Option: 0.3

Do education programs for preschool children that follow the Montessori method perform better than other programs? A study compared five-year-old children in Milwaukee, Wisconsin, who had been enrolled in preschool programs from the age of three. All the children in the study applied to the Montessori school. The school district assigned students to Montessori or other preschools by a random lottery. (a) Comparing children whose parents chose a Montessori school with children of other parents would not show whether Montessori...

Will rate!!
People who eat lots of fruits and vegetables have lower rates of colon cancer than those who eat little of these foods. Fruits and vegetables are rich in "antioxidants" such as vitamins A, C, and E. will taking antioxidants help prevent colon cancer? A medical experiment studied this question with 864 people who were at risk of colon cancer. The subjects were divided into four groups: daily beta-carotene, daily vitamins C and E, all three vitamins every day,...

The first two questions refer to the following information: Researchers developed an online tool to help ESL students learn prepositions and metaphors. A study measuring academic success in ESL students randomly sampled 100 Spanish speaking ESL students using traditional ESL classes and the new language tool and 81 Portuguese speaking ESL students using traditional ESL classes and the new language tool, and scored them on a common English fluency scale (higher score representing greater degree of fluency). The researchers suspected...

The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
